A16z partner says that the theory that we’ll vibe code everything is wrong

2/20/2026 at 11:42:09 PM

Even a16z is walking this back now. I wrote about why the “vibe code everything” thesis doesn’t hold up in two recent pieces:

(1) https://philippdubach.com/posts/the-saaspocalypse-paradox/

(2) https://philippdubach.com/posts/the-impossible-backhand/

Acharya’s framing is different from mine (he’s talking book on software stocks) but the conclusion is the same: the “innovation bazooka” pointed at rebuilding payroll is a bad allocation of resources. Benedict Evans called me out on LinkedIn for this (https://philippdubach.com/posts/is-ai-really-eating-the-worl...) take, which I take as a sign the argument is landing..

The best take I've seen on the whole `AI will replace all devs' is a way for big tech to walk back the disastrous over hiring they did around Covid without getting slaughtered in the stock market.

The market doubly rewards companies that lay off workers and have a story about how they're automating everything with AI, even if that story is just a story.

> investors are simultaneously punishing hyperscaler stocks because AI capex might generate weak returns, while destroying software stocks because AI adoption will be so pervasive it renders all existing software obsolete. Both cannot hold simultaneously.

I don't understand this point. Can't it be possible that the ultimate effect is to devalue, hugely, software? As in it can totally both be true that AI capex has weak returns and at the same time most SaaS companies go bankrupt. To take an analogy: if ever we manage to successfully mine asteroids, and find some vast quantity of platinum, it could both be true that every existing platinum miner loses their shirt, and also that the value of platinum sinks so far that the asteroid mining company cannot cover its costs.

by re-thc

2/22/2026 at 10:18:00 AM

It is an AI thing though. AI makes it far easier to create bespoke software targeted at narrow specialized domains, which is the mainstay of modern SaaS. We'll probably see "proper" FLOSS expand into these sectors too, such that the software won't be simply a matter of internal vibecoding by any single business - instead, the maintenance work will be shared.

by zozbot234

2/22/2026 at 12:33:04 PM

AI makes it easier to create something, but that thing is not enterprise software with support contracts and conformance to mandatory regulations and 4 hour bug turnarounds and real people on the end of the phone who understand how it works.

Sometimes I just wonder at how HN has no idea what enterprise software involves.

by rwmj

2/22/2026 at 1:17:28 PM

With this kind of niche sector-specific offering, creating a prototype that works properly for what the industry needs is the main hurdle. The rest is just the same sort of ordinary software engineering work that applies to any FLOSS project already - and we know that FLOSS (with optional 3rd party support covering "enterprise" needs) is quite viable.

by zozbot234

2/22/2026 at 2:44:54 PM

I don't see AI easily creating a DataDog. You need it for reliability for example.

You can always also deploy open source since forever. What happens when it randomly drops logs or changes the text? If you get an alert and it is noise it starts becoming pointless.

And yet these type of stocks were at 50-100x earnings etc.

How is AI code generation a "innovation bazooka"? Last time I checked, innovation required creativity, context, and insight. Not really fast boilerplate generators.

by Derbasti

2/22/2026 at 4:15:10 PM

AI allows innovative people to create more innovations by reducing a lot of the non-innovative grunt work in an efficient manner. It isn't the AI doing the innovation, but allows innovators to focus more on innovating.

Or at least that is the theory. It is certainly true from observations of those around me. It also scales well. Even someone a bit innovative gets a multiplier by using AI intelligently. Those that just focus on the grunt work are the ones in trouble.

by gilbetron

2/22/2026 at 9:37:40 AM

All that is correct and well-written, however I fear in most cases "good enough" will be good enough for Business. If Business can do something to 80% the same but with a large cost cutting they likely go for it, we have seen this with shrinkflation (reduced portion sizes for the same price), to using cheaper ingredients to practically everything that is not a knowledge-heavy industry. The big change is now the "shrinkflation" is coming to knowledge domains too, which will likely lower the quality of healthcare, software etc.

AI being a next-token predictor will produce cheap and average products, we will likely see some (most?) software become a commodity, that goes through the same product development and "manufacturing" as a breakfast cereal. Made in a "dark factory", 24/7, with little supervision.

However I think down the line we will see many industries popping up that are like "organic food", "mechanical watchmaking" that provide above the usual slop that large businesses produce.

Using vibe coding to build a small specialized tool for a small company that can be used instead of single feature of a commercial SaaS is doable and brings value.

Using vibe coding to build something to replace an enterprise SaaS offering for a medium to large company is not something to be taken lightly. The tool and the code is not everything. The operating environment, security guarantees, SLAs, support, and a bag of features you don't need today but might tomorrow is what the SaaS offerings bring to the table.

Imagine that I run a really good software house. I can literally build anything you want, feature wise, better than most. I do it quickly. You come to me and say you want to replace Slack for your team of 200, because Slack got too expensive. I say I can do it. Because I am feeling generous and you're my good friend, I will do it for free. However, I will just give you the code, a CI/CD script, and a README.md file. I will disappear and will not maintain or support your software, nor will I give you any guarantees on how well it will work, other than a "trust me."

I wouldn't take the offer.

by koliber

2/22/2026 at 4:31:54 PM

The question is how much further and faster can these tools evolve.

Right now, you may not be faced with a valid choice to vibe code your own hubspot, but maybe some contractor firm will do it for you and sell an ultra low cost version.

Will opus 6 do the same thing without the contractors while managing the deployment and maintenance as a claw?

by lumost

2/22/2026 at 1:13:43 PM

The Matrix folks have covered the "replace Slack internal chat" case already. They will give you the code so that you can bring the service up internally, or you can use any 3rd party hosted solution that provides the usual support and "enterprise" guarantees, for a price. Why can't this model generalize to sector-specific SaaS offerings that can now be prototyped cheaply via AI vibecoding?

People are overestimating the value on having AI create something given loose instructions, and underestimating the value of using AI as a tool for a human to learn and explore a problem space. The bias shows on the terminology (“agents”).

We finally made the computer able to speak “our” language - but we still see computers as just automation. There’s a lot of untapped potential in the other direction, in encoding and compressing knowledge IMO.

by manoDev

2/22/2026 at 4:16:14 AM

by preommr

2/22/2026 at 1:41:41 AM

Exactly my thoughts - the value in AI is not auto-generating anything more than something trivial, but there's huge value in a more customized knowledge engine - a targeted, specific Google if you will. Get answers to your specific question instead of results that might contain what you were looking for if you slog through them.

AI is hugely beneficial in understanding a problem, or at least getting a good overview, so you can then go off and solve/do it yourself, but focusing on "just have the AI generate a solution" is going to hugely harm AI perception/adoption.

I once built a CRM in Google Sheets fully mirroring the data model of Salesforce. For contact, company, deal, and call tracking for a one sales rep business. (Before XLookup was in Google Sheets)

Did it work? Yes. Was it worth my time to maintain and scale the “platform” with the company rather than outsource all that to a CRM company? Not at all.

Yup, my experience has been that vibe-coding is very time-consuming. It reminds me very much of how LLMs are great at creating mind-blowing images, but you get what you get. Once you decide that you need to modify the image you get, it becomes a time sink. You might be able to change it and get what you need, but there is no guarantee and it's a never ending task.

The same thing happens with code; you may get great results from your prompt, but trying to customize it will drive you nuts and you may never get what you want.

Maintenance is another hurdle. How do you maintain code you might not have the skills to maintain?

Vibe-coding may reduce software creation time, but it's not taking over software engineering. The SaaS business is going nowhere. Most people, by far, will continue to rely on someone else for their software needs. But be very aware that the software business will change. We are seeing that already.

by WheelsAtLarge

It doesn't make sense for every company to make their own Salesforce clone.

The key is that it makes new companies entering the market to compete with Salesforce immensely easier. More competition will just force lower overall margins in SAAS.

by zhivota

2/22/2026 at 2:55:30 PM

But a query optimizer only matters once you have an established business with large customers.

by hippo22

2/22/2026 at 12:01:49 PM

It was never the only hard part, but it definitely was a hard part (at least in most cases; obviously there are some monopolies with relatively simple software - mostly where there are network effects like WhatsApp).

But give me the source code for something competitive with Solidworks, Jasper Gold, FL Studio, After Effects, etc. and I'm sure as hell making a business out of it!

Furthermore while good software may not guarantee business success, it is pretty much a requirement. I have seen many projects fail because the software turned out to be the hard part.

The missing piece in this debate is that most "vibe coded" replacements break at scale. I tried replacing a multi-step workflow with Make.com + Airtable (not even vibe coding, just no-code automation) and it fell apart past 2 jobs per day - rate limits, webhook failures, state management nightmares. The real pattern I see working is not "replace SaaS with vibe code" but rather "stitch together 5-6 specialized tools with a thin orchestration layer you write yourself." The orchestration is where AI actually helps - it's glue code, not the product.

by umairnadeem123

2/22/2026 at 3:07:49 AM

Thought exercise for those in disagreement: why would every company use AI to build their own payroll/ERP/CRM, when just a handful of companies could use AI to build those offerings better?

This is largely how things work now; AI may lower the cost and increase margins, but the economics of build vs buy seem the same.

by aobdev

2/22/2026 at 3:43:35 AM

To avoid CRAZY SaaS charges. I left a comment further down about how the challenge is first getting a reliable stack running underneath whatever ends up being fast-coded. The trend will be more decentralization - I think that'll be AI 2.0. Increasing centralization is AI 1.0.

by adrianwaj

2/23/2026 at 3:51:25 AM

But if that was a goal, or a marketable feature, SaaS and cloud would have competitors out there selling software with perpetual licenses to be run on premises

Yes, the vendors want subscriptions and cloud and not owning anything, but customers also don't want to hire people to operate the infrastructure required to run this stuff themselves. That's the whole point of SaaS, and why some companies just run entirely on that model and basically have no in-house IT staff

That AI means you can write and run your own payroll system doesn't mean all of a sudden a world of people with zero technical skills can start doing it on their own

by mixdup

...unless they have an agent "IT Guy" who can either do it for them or show them what to do. Perhaps UIs will change and be designed half for a human operator, and half for the IT Guy to copilot with them.

The person with zero technical skills could start learning primitive technology: youtube.com/@primitivetechnology9550 - living off the land really is the job for the unemployed. We've done it before!

by adrianwaj

2/22/2026 at 3:35:02 AM

Well the answer is because the cost of that software is lower than somebody building the other software. What happens is that all these SaaS drop in value because it is now realistic to build them internally

by Fire-Dragon-DoL

2/22/2026 at 3:51:17 AM

Why does AI make it cheaper to build internal but not cheaper for SaaS competitors to pop up? Everyone has access to the same tools.

by aobdev

2/22/2026 at 4:20:24 AM

Oh sure! My conclusion is that they will drop in value, not disappear.

Basically I expect way smaller companies popping up competing with the big ones and their offering will be priced way lower because their payroll is way smaller.

While there is no competitor, internal tools will pop up now.

by Fire-Dragon-DoL

2/22/2026 at 4:42:28 AM

I believe that. Companies will build cheap tools today while competitors are spinning up to undercut ADP, Salesforce, and SAP. But what happens tomorrow? There are plenty of examples in IT today where the reasonable option is to outsource in 90% of cases: don’t roll your own auth, don’t host your own email server, don’t build your own data center. I don’t see how AI can change that, when the people who build specialized software also have access to AI.

Another great example is open source. I think PostgreSQL being free and usable by everyone is a more economic outcome than every Fortune 500 company building their own database engine. Payroll, ERP, and CRM fall into the same category of being commodity software in a lot of cases.

by aobdev

2/22/2026 at 12:15:46 PM

My experience is that the folks in charge of spending and making decisions are looking at AI as another means of outsourcing. Payroll, ERPs and CRMs went from commodity software to subscription services and anything that is subscription based is getting scrutinized much more heavily now.

by gnz11

It does make it cheaper, obviously. But the barrier to entry is almost zero, like panhandling. That's why it can't substitute a job.

Every company that I’ve worked at has had to do significant additional development work on their instance of salesforce to make it work for them. Like 6-12 months of work with 1-3 people. I don’t know if this is common but in that case maybe going custom might be the way to go. You get something lean, without all the cruft, specifically built for your usecase and nothing more.

Slack is a good example. When the cost of Slack is an unreasonable amount of your operating costs then it makes sense to clone and maintain. The product is simple, you can basically recreate the main functionality in a sitting. Why would you pay hundreds of thousands of dollars for it?

by pmmucsd

2/22/2026 at 3:49:49 AM

That’s a fine example, but my question then is why does Slack exist? Surely Fortune 500 companies are smart enough to realize that building a slack clone is cheaper, yet they don’t do that.

So now consider AI, perhaps the cost of building has decreased from 100k to 10k. What stops a Slack competitor from also building the product for 10k and reselling it at 10% of the cost of Slack? My point is that I don’t see how AI has changed the value prop.

by aobdev

2/22/2026 at 9:46:38 AM

> my question then is why does Slack exist?

I do not actually believe that you can trivially vibe code a viable slack replacement. But even if one day we could it wouldn’t mean that Slack as a company would just disappear overnight.

They would hang around serving companies who haven’t got the memo yet, or who are locked in a contract, or where the internal political situation is against such a move. The innertia of a bunch of humans behaving like a bunch of humans would provide a sort of “coyote time” effect where the fundamentals could fall out from under Slack yet the company would keep “floating” for a while.

It is funny how much of your question sounds like the old joke where an economist can’t believe their eyes that a $20 bill is laying on the pavement, because surely if it were so someone would have already picked it up. In a steady state the logic might hold up, but we are not in a steady state.

And that is separate from why do I think it is not realistic to just replace slack with vibe coded alternative: just in my company some people use the web interface, some the ios app and some the android app. To be a viable replacement you would need all 3 platforms supported with all features. That sounds in itself a nightmare. Then figuring out what features my company members really use is an other nightmare. There are some who craft custom emojis all the time, some who integrate all kind of weird apps. We various CI and data pipeline processes integrated with slack reporting. And then comes huddle. Video and voice chat and screen sharing. You can even draw on someone else’s screen with it! IT has their needs to archive things (maybe?) or snoop on certain things. Then comes of course interfacing with single-sign-on. I wouldn’t even volunteer to enumerate all the different features people just at my company depend on, let alone offer to replace it.

by krisoft

2/22/2026 at 4:55:54 AM

There is value in taking a product to market and hardening it, and no one wants to invest in something that requires headcount for cost-savings. They want upside. But if it doesn't require headcount and/or unlocks functions they have to negotiate for, and the AI can keep it online and troubleshoot, that is a different story.

Slack exists in part because ten years ago it was a lot harder for big orgs to make good/modern software.

by svnt

2/22/2026 at 4:06:19 AM

I don’t doubt it but that doesn’t negate the fact that Slack as a company exists and makes money by selling software. My question is this: AI makes it cheaper to build software, but ADP, SAP, and Salesforce also have access to AI and could make cheaper versions of their products. How does AI change the build vs buy trade off in a way that eliminates economies of scale? My opinion and that of the article is that it doesn’t.

by aobdev

2/22/2026 at 4:48:01 AM

> How does AI change the build vs buy trade off in a way that eliminates economies of scale?

I think a more likely scenario here is that something good and free escapes containment at some point and Slack’s core product just kind of deflates. Not something better than Slack, but something good enough that people don’t care about Slack any more.

I don’t see it as a question of whether you build it or buy it, but a question of the time horizon for selling messaging software as a business strategy. Most business strategies have a finite time horizon. How long can you continue to sell messaging software before there are too many competing solutions available and you stop making money from it?

2/22/2026 at 9:22:45 PM

Kind of like databases and web servers, then?

I don’t think “categorically different” has legs. I work on the operations & hosting side of applications like this. There’s an operations burden to maintain, deploy, and scale web servers. There’s a burden to rolling out new Linux kernel versions to servers. But we still do it! There would be a burden to running your own Slack, just like there is a burden to running your own email, and people will choose to pay for hosted versions or host it themselves.

And then there are companies and organizations who have strong incentives to self-host to make compliance easier.

A list of outcomes:

2. They did, and then exited the market. Employees gradually migrated off the internal platform.

3. They weren’t in the business of selling software, and didn’t sell their internal messaging platform (which is idiosyncratic and closely integrated with other internal system).

by klodolph

You don't need AI for a cheap slack alternative.

That's why I don't buy any of this.

Until you can get AI to the point where it equivalent to a 20 person engineering team, people are not going to build their own Snowflake, Salesforce, Slack or ATS. Maybe that day is 3 years away but when that happens the world will be very different

Companies do make/buy decisions on everything, it just software. Cleaning services are not expensive, yet companies contract them instead of hiring staff.

This is called transaction cost economics, if anyone’s interested.

We’ve also got to consider the fourth dimension, what happens over time.

Salesforce is getting LLM superpowers at the same time the Enterprise is, so customizing and maintaining and extending Salesforce are all getting cheaper and better and easier for customers, consultants, and Salesforce in parallel.

Unless the LLMs are managing the entire process there’s still a value proposition around liability, focus, feature updates, integrations, etc. Over time that tech should make Salesforce get way cheaper, or, start helping them upsell bigger and badder Sales things that are harder to recreate.

And, big picture, the LLMs are well trained on Salesforce API code. Homegrown “free” versus industry-standard with clear billing, whatever we know versus man-decades of learning at a vendor, months of effort and all the risk & liability versus turnkey with built-in escape goats… at some point you’re paying money not to own, not to learn, not to be distracted, and to have jerks to sue if something goes bad.

I agree generally, but some of these enterprise contracts are eye-watering. If the choice is $2M/year with a 3-year minimum contract, or rolling your own, I think calculus really has shifted.

With that said, the entire business world does not understand that software is more than just code. Even if you could write code instantly, making enterprise software would still take time, because there are simply so many high-stakes decisions to make, and so much fractal detail.

> If the choice is $2M/year with a 3-year minimum contract, or rolling your own, I think calculus really has shifted.

But why? It was always dramatically cheaper for enterprises to build rather than buy. They stopped doing that becuase they did that in the 90s and ended up with legacy codebases that they didn't know how to maintain. I can't see AI helping with that.

by nicoburns

This might be the biggest benefit of AI coding. If I have a large legacy code base I can use AI to ask questions and find out where certain things are happening. This benefit is huge even if I choose not to vibe code anything. It ends up feeling a lot like the engineer that wrote the code is still with you or documented everything very well. In the real world there is a risk that documentation is wrong or that the engineer misremembers some detail so even the occasional hallucination is not a particularly big risk.

If you consider total cost of ownership including long-term maintenance costs, it means building has not always been cheaper than buying. I think what's changing is that it's now becoming dramatically cheaper to build AND operate AND maintain "good enough" bespoke software for a lot of use cases, at least in theory, below a certain threshold of complexity and criticality. Which seems likely to include a sizeable chunk of the existing SAAS market.

I can't believe I'm saying this, but I guess you don't even really need to maintain software if it's just a tool you hacked together in a week. You can build v2 in another week. You'll probably want to change it anyways as your users and your org evolve. It's a big question for me how you maintain quality in this model but again, if your quality standard is "good enough", we're already there.

by xoz123

2/22/2026 at 3:45:02 PM

Oh I don't know, I think AI is very helpful at maintaining and modernizing legacy codebases. And in the old days, the "build" option was often not really cheaper once you factored in four salaries for developers to maintain the product. But now…

Exactly. I was building an app to track bike part usage. It was an okay app, but then I just started using ai with the database directly. Much more flexible, and I can get anything I need right then. AI will kill a lot of companies, but it won’t be the software it develops, it will be the agent itself

by rckclmbr

2/22/2026 at 3:34:22 AM

Do you run the app locally?

If it's not local, I saw this comment: https://news.ycombinator.com/item?id=47085906

"This entire stack could give you computing power equivalent to a 25k euro/month AWS bill for the cost of electricity (same electricity cost as running a few fridges 24/7) plus about 50k euros one-time to set it up (about 4 Mac Studios). And yes, it's redundant, scalable, and even faster (in terms of per-request latency) than standard AWS/GCP cloud bloat. Not only is it cheaper and you own everything, but your app will work faster because all services are local (DB, Redis cache, SSD, etc.) without any VM overhead, shared cores, or noisy neighbours."

Makes me think there will be these prompts like "convert this app to suit a new stack for my hardware for locally-optimized runtime."

How are people building the best local stacks? Will save people a ton of money if done well.

If an AI agent ever became as productive at writing code as a well-organized 20 person engineering team you'd still need to run it for a year or more to replicate any nontrivial SaaS product.

And the thing about many of these products isn't their feature set, it's their stability. It's their uptime. It's how they handle scaling invisibly and with no effort on your part. These are things you can't just write down from whole cloth, they are properties that emerge over time by adapting the the reality of scale. Coding isn't the whole deal, and your 20x clanker which can do nothing but re-arrange text in interesting patterns is going to have some trouble with the realities of taking that PoC to production. You'll still need experienced, capable people for that. And lots of time.

A lot of this "ermahgerd everything will change" drivel is based on some magical fundamentally new technology emerging in the near future that can do things that LLMs cannot do. But as far as anyone knows, that future may be never.

So even given a large improvement in agentic coding I'm not convinced it really changes the build vs buy equation much.

by jcgrillo

2/22/2026 at 3:57:44 AM

I sort of agree with this, but what a lot of people are missing is it's unbelievably easy to clone a lot of SaaS products.

So I think big SaaS products are under attack from three angles now:

1) People replacing certain systems with 'vibe coded' ones, for either cost/feature/unhappiness with vendor reasons. I actually think this is a bigger threat than people think - there are so many BAD SaaS products out there which cost businesses a fortune in poor features/bugs/performance/uptime, and if the models/agents keep improving the way they have in the last couple of years it's going to be very interesting if some sort of '1000x' engineer in an agent can do crazy impressive stuff.

2) Agents 'replacing' the software. As people have pointed out, just have the agent use APIs to do whatever workflow you want - ping a database and output a report.

3) "Cheap" clones of existing products. A tiny team can now clone a "big" SaaS product very quickly. These guys can provide support/infra/migration assistance and make money at a much lower price point. Even if there is lock in, it makes it harder for SaaS companies to keep price pressure up.

by martinald

2/22/2026 at 4:18:42 AM

But have you ever tried to clone a product or tool for yourself before? At first it’s great because you think that you saved money but then you start having to maintain it… fixing problems, filling in gaps… you now realize that you made a mistake. Just because AI can do it now doesn’t mean you aren’t just now having to use AI to do the same thing…

Also, agents are not deterministic. If you use it to analyze data, it will get it right most of the time but, once in a blue moon, it will make shit up, except you can’t tell which time it was. You could make it deterministic by having AI write a tool instead… except you now have the first problem of maintaining a tool.

That isn’t to say that there isn’t small low hanging fruit that AI will replace, but it’s a bit different when you need a real product with support.

At the end of the day, you hire a plumber or use a SaaS not because you can’t do it yourself, but because you don’t want to do it and rather want someone else who is committed to it to handle it.

by harrall

2/22/2026 at 4:25:32 AM

I'm not saying _the end user_ clones it. I mean someone else does (more efficiently with agents) and runs it as a _new_ SaaS company. They would provide support just like the existing one would, but arguably at a cheaper price point.

And regarding agents being non deterministic, if they write a bunch of SQL queries to a file for you, they are deterministic. They can just write "disposable" tools and scripts - not always doing it thru their context.

by martinald

2/22/2026 at 4:52:28 AM

The challenge to this is that so much of the difficulty in getting people to switch products is trust, and a couple of people running saas with claude code has no differentiation and no durability.

I think it will be a little different: black box the thing, testable inputs and outputs, and then go to town for a week or two until it is reasonable. Then open source it. Too big/complex for an agent? Break down the black box into reasonable ideas that could comprise it and try again. You can replace many legacy products and just open source the thing. If the customer can leave behind some predatory-priced garbage for a solution where they get the code I think they would be a lot more likely to pay for help managing/setting it up.

It would be interesting if, with all the anxiety about vibe coding becoming the new normal, its only lasting effect is the emergence of smaller B2B companies that quickly razzle dazzle together a bespoke replacement for Concur, SAP, Workday, the crappy company sharepoint - whatever. Reminds me of what people say Palantir is doing, but now supercharged by the AI-driven workflows to stand up the “forward deployed” “solution” even faster.

I do think that I have worked on somewhat complex code bases. The reason why they are complicated is often "political" (e.g. at some point it was decided that this is the way to go, and from then on the specific abstraction was used. It turned out these wishes were not a good idea, but the code was never re-developed with a "more proper" architecture (also for the reason that removing some insanely convoluted feature would anger some users)).

I see no reason why some (hypothetical) AI couldn't come up with a much better architecture (also good programmers are capable of this). The problem is rather "getting this architecture through politically"; for some reason "AI suggested/created it" is much more socially accepted by managers than "programmer X considers this change to be necessary" (I cannot understand why).

by aleph_minus_one

it can but it will take one person just as long as a small team without "AI" and that one person will carry all the frustration, doubt, all the to do lists and imaginary pin boards and all that other stuff programmers carry around in their heads, at work and back home. have fun with all that.

side note: indie games are not complex software.

and most "overvalued" and "impossible" and "walking it back now" comments are true in as many cases as they are not true and I really do not understand these commenters. smart people should not fall into the same category as people who think that "nobody cares" because they never met devoted lawyers, investigative journalists and law enforcers passionate about justice AND law. it's all so weird, man ...

The bottleneck will always be humans. You could get AI to write a million lines of code a day, but you’d still need humans to review and test that code. We are a very long way from being able to blindly trust AI’s outputs in production.

by dabinat

2/22/2026 at 7:04:10 AM

I don’t even think it’s about reviewing and testing. The bottleneck will always be humans.

We don’t like to always admit it but most jobs are fairly straightforward, as in the actual day to day tasks. Yes being smart is great and useful etc. but after a certain point it’s diminishing returns on the actual tasks you have to do. Dealing with other humans and their egos and eccentricities and the multitude ways each person sees the world is always what makes all jobs tricky. I suspect this whole ai wave/hype/reality is going to open many people’s eyes to this. We will laugh that we use to call them “soft” skills.

IMO I would have agreed with this statement 2 months ago but now it’s clear AI is already much better at reviewing and even testing code (via spinning up simulators, etc) much better than we can. We’re already using AI’s outputs in production and not writing much code these days.

by acuozzo

2/22/2026 at 1:26:32 PM

AI assisted coding is going to make it easier to create software. Developers will be more productive. Non developers will be able to create some stuff.

What this means is that very simple apps will become easy to create quickly. So a todo manager is probably not going to be a very successful business. You’ll be competing with many many people and it will be commoditised.

But ultimately what happens here is the “complexity threshold” of a sufficiently complex product needed to make money will be raised. Existing products will become more sophisticated or, if there is not more “sophistication ladder to climb” then they will be commoditised.

There’s just no way people are going to vibe all their software, that’s a very self absorbed nerd take. But on the supply side we’ll see commoditisation, price drops, and increasingly good value for the user as features are shipped faster.

I also think that software quality is really going to tank, because using validation to test the output of Claude is not a good way to ensure quality or correctness. It’ll get you some of the way but you need powerful reasoning. The most obvious evidence for this is security flaws in AI code. We’ll see a new era of enshitification caused by AI code. Like outsourced manufacturing though, people will buy worse stuff at a cheaper price. That makes me sad, because I thought we were on a path to better software, not buggier software.

Both AI Fanatics and AI Luddites need to touch grass.

We work in Software ENGINEERING. Engineering is all about what tools makes sense to solve a specific problem. In some cases, AI tools do show immediate business value (eg. TTS for SDR) and in other cases this is less obvious.

This is all the more reason why learning about AI/ML fundamentals is critical in the same way understanding computer architecture, systems programming, algorithms, and design principles are critical to being a SWE, because then you can make a data-driven judgment on whether an approach works or not.

Given the number of throwaway accounts that commented, it clearly struck a nerve.

by rsrsrs86

2/21/2026 at 8:24:30 AM

There is a lot of work that goes on before even reaching the point to write code.

For example, being able to vibecode a UI wireframe instead of being blocked for 2 sprints by your UI/UX team or templating an alpha to gauge customer interest in 1 week instead of 1 quarter is a massive operational improvement.

Of course these aren't completed products, but customers in most cases can accept such performance in the short-to-medium term or if it is part of an alpha.

This is why I keep repeating ad nauseum that most decisionmakers don't expect AI to replace jobs. The reality is, professional software engineering is about translating business requirements into tangible products.

It's not the codebase that matters in most cases - it's the requirements and outcomes that do. Like you can refactor and prettify your codebase all you want, but if it isn't directly driving customer revenue or value, then that time could be better spent elsewhere. It's the usecase that your product enables which is why they are purchasing your product.

by alephnerd

2/22/2026 at 1:18:02 AM

  > The reality is, professional software engineering is about translating business requirements into tangible products.

and most requirements (ime anyways) are usually barely half-baked and incomplete causing re-testing and re-work over and over which are the real bottlenecks...

ai/vibe coding may make that cycle faster but idk it might actually make things worse long-term because now the race course has rubber walls and there is less penalty just bouncing left and right instead of smoothly speeding down the course to the next destination...

By making the cycle faster it reduces the impact while also highlighting issues within the process - there are too many incompetent PMs and SWEs.

Additionally, in a lot of cases a PM won't tell you that you might actually be working on checkbox work that someone needs to do but doesn't justify an entire group of 2-3 SWEs because then you obviously won't do the work. This kind of work is ripe for being automated away via vibecoding or agents.

A good reference for this is how close is the feature you are working on directly aligned with revenue generation - if your feature cannot be directly monetized as it's own SKU or as a part of a bundle, you are working on a cost center, and cost centers are what we want to reduce either by automating them away, offshoring them, or doing a mix of both.

The reality is that perfection is the enemy of good, and this requires both Engineers and PMs working together to negotiate on requirements.

If this does not happen at your workplace, you are either working on a cost center feature that doesn't matter, you are viewed as a less relevant employee, or you are working at a bad employer. Either way it is best for you career to leave.

In my experience, if you've actually chatted with executive leadership teams in most F500s, when they are thinking about "AI Safety" they are actually thinking about standard cybersecurity guardrails like zero-trust, identity, authn/z, and API security with an added layer of SLAs around deterministic output.

But by being able to constantly interate and experiment, companies can release features and products faster with better margins - getting a V1 out the door in 1 sprint and spending the rest of the quarter adding guardrails is significantly cheaper than spending 1 quarter building V2 and then spending 1 more quarter building the same guardrails anyhow.

Basically, we're returning to the same norms in the software industry that we had pre-COVID around building for pragmatism instead of for perfection. I saw a severe degradation in the quality of SWEs during and after COVID (too many code monkeys, not enough engineers/architects).

by alephnerd

2/23/2026 at 2:28:35 AM

i think that is the ideal situation, but i am probably a bit pessimistic from my experience; i feel like people will experiment more but it will be more like throwing things at the wall to see what sticks instead of more focused customer research (by devs or pm/pdms alike)... anyways just my feels...

  > reality is that perfection is the enemy of good

not to take too much from your point, but i would slightly modify this to something like "perfection is the enemy of good but good can be the enemy of what is needed"; we should know what the customer needs and build that, not just something (more) good... sorry for the pedantry lol we are probably not disagreeing here but anyway

Using non-deterministic LLMs to vibe code applications is a “workshop” activity - meaning it is iterative and the greater the complexity, the more complex it is to workshop the fixes. At some stage you realize that while you’re blown away by how sophisticated the LLM is, playing go-fish with it is a larger time suck than you expected. It’s like being asked to read a friend’s term paper only to find it’s beyond saving and you just say “good job”. Now scale this up to ever evolving, highly complex systems that have to work with five-nines regularity. When we don’t need the humans to workshop the fixes, things will be different.

by ars-machina

2/22/2026 at 5:54:16 AM

It seems to be premised on the idea we would vibe code a replica of what we get from SaaS. But the real point is, we would not do that. We would vibe code something that exactly fits our business.

We have products we're paying $100k a year for and using 3% of the functionality. And they suck. This is the target.

by obiefernandez

2/21/2026 at 10:43:22 PM

I don't understand this because who's gonna maintain it in the future? Surely that costs more to pay even one person to add features that Linear had than to pay Linear themselves. I'd do this for personal projects but never for my work company lest I be the one to maintain it indefinitely on top of my current work.

by satvikpendem

2/22/2026 at 12:33:29 AM

one thing annoying with premade solutions is that it only does 90% of what you want, its livable but still doesn't quite meet your needs.

Its not just adding features that Linear already provides but adding features and integrations that mets 100% your needs.

The full decision making equation is (cost of implementing it yourself + cost of maintenance + 10% additional benefit for a solution that fully meets your needs) versus (cost of preexisting solution that meets 90% of your needs). Cost of implementing it and cost of maintenance has just gone down. Surely that will mean on a whole more people as a whole will choose to make inhouse rather than outsource.

Thus demand for premade solutions will go down, Saas providers won't be able to increase their prices as this will make even more people choose to implement it themselves. The cost of producing software will continue to drop due to agentic coding and maintenance cost will drop as well due to maintenance coding agents. More people will choose their own custom solutions and so on. Its very possible we are in the beginning of the end for Saas companies.

All these articles seem to think people will vibe code by prompting:

make me my own Stripe

make me my own Salesforce

make me my own Shopify

It will be more like:

Look at how Lago, an open-source Stripe layer, works and make it work with Authorized.net directly

Look at Twenty, an open-source CRM, and make it work in our tech stack for our sales needs

Look at how Medusa, an open-source e-commerce platform, works and what features we would need and bring into our website

When doing the latter, getting a good enough alternative will reduce the need for commercial SaaS. On top of that, these commercial SaaS are bloated with features in their attempt to work with as many use cases as possible and configuring them is “coding” by another name. Throw in Enshittification and the above seems to the next logical move by companies looking to move off these apps.

by theturtletalks

2/21/2026 at 4:18:02 AM

The value in enterprise SaaS offerings isn't just the application functionality but the IaaS substrate underneath. The vendor handles server operations, storage, scalability, backups, security, compliance, etc. It might be easier for companies to vibe code their own custom applications now but LLMs don't help nearly as much with keeping those applications running. Most companies are terrible at technical operations. I predict we'll see a new wave of IaaS startups that sell to those enterprise vibe coders and undercut the legacy SaaS vendors.

The right move is this, turned to 11.

Velocity or one-shot capability isn't the move. It's making stuff that used to be traumatic just...normal now.

Google fucking vibe-coded their x86 -> ARM ISA changeover. It never would have been done without agents. Not like "google did it X% faster." Google would have let that sit forever because the labor economics of the problem were backwards.

That doesn't MATTER anymore. If you have some scratch, some halfway decent engineers, and a clear idea, you can build stuff that was just infeasible or impossible. all it takes is time and care.

Some people have figured this out and are moving now.

by selridge

2/21/2026 at 8:00:30 PM

I think something like an x86 -> ARM change is perfect example of something where LLM assisted coding shines. lots of busywork (i.e. smaller tasks that don't require lots of context of the other existing tasks), nothing totally novel to do (they don't have to write another borg or spanner), easy to verify, and 'translation'. LLMs are quite good at human language translation, why should they be bad at translating from one inline assembly language to another?

by est31

2/21/2026 at 9:10:39 PM

Yeah. Lots of busywork where if you had to assign it to a human you would need to find someone with deep technical expertise plus inordinate, unflagging attention to detail. You couldn’t pass it off to a batch of summer interns. It would have needed to be done by an engineer with some real experience. And there is no way in the world you could hire enough to do it, for almost any money.

by selridge

2/21/2026 at 9:46:33 PM

You've missed the subtlety here.

LLMs don't have attention to detail.

This project had extremely comprehensive, easily verifiable, tests.

So the LLM could be as sloppy as they usually arez they just had to keep redoing their work until the code actually worked.

by mattmanser

2/22/2026 at 5:49:17 AM

I missed the subtlety?

I linked the paper! I read the paper. Yeah. they wrote the tests, which is how this worked! how the heck do you think it was supposed to work?

the fact that they needed to write the tests was just the means to implementation. It didn't change the non-LLM labor economics of the problem.

by selridge

2/22/2026 at 8:55:10 AM

No, I meant subtlety of definition, you've attributed the diligence to the LLM when in fact it's the tests that provide that.

You've unfortunately committed the big sin of anthropomorphizing the LLM and calling it diligent.

An LLM cannot be diligant, it's stochastic so it's literally impossible for it to be diligant.

Writing all those tests was diligant.

by mattmanser

2/22/2026 at 3:39:44 PM

I didn’t attribute diligence to anything.

I’m not worried about the personal character of diligence. I’m interested in what the technology unlocked and how things made with it are materially different in terms of labor configurations.

And how does the answer to your question bear on the claim I’m making?

by selridge

2/22/2026 at 4:24:17 PM

If you're trying to automate all coding activity, writing tests is coding activity. Arguably the greater fraction of effort between implementation, and verifying said implementation. If the only thing making your problem space tractable for the automation to be able to replace the lesser half of coding activity is an authored test suite you couldn't generate via your automation, then you really need to admit that.

"Did you check?" is the most expensive question, and one of the most feared in my experience in tech circles. Spent quite a few years as a dedicated tester once I developed the knack for it. Everybody gangsta til it's time to prove the damn thing works.

by salawat

2/22/2026 at 5:08:11 PM

> "Did you check?" is the most expensive question, and one of the most feared in my experience in tech circles.

Here it’s a climb-down. Writing tests to validate translation is orders of magnitude less work (and less likely to fail or be too dull to do properly) than the alternative available prior to 2025.

The fact that they wrote tests and clearly established operational control is not some kinda gotcha! It’s how they managed to get this piece of technology to allow them to do the IMPOSSIBLE.

I am just really struggling to understand someone who reads that paper and thinks “yup, everything is still the same and we don’t need to re-evaluate any ideas” Like, if you want to say that they still need engineering discipline in order to do ISA transitions at scale then…ok? That’s true? But Gemini meant that this formerly impossible thing was now not only within reach but done.

by selridge

2/21/2026 at 2:19:30 AM

Exactly, if the engineers know where to look for the solution in open-source code and point the AI there, it will get them there. Even if the language or the tech stack are different, AI is excellent at finding the seams, those spots where a feature connects to the underlying tech stack, and figuring out how the feature is really implemented, and bringing that over.

I highly doubt that, and its in OPs article.

First, a vendor will have the best context on the inner workings and best practices of extending the current state of their software. The pressure on vendors to make this accessible and digestable to agents/ LLMs will increase, though.

Secondly, if you have coded with LLM assistance (not vibe coding), you will have experienced the limited ability of one shot stochastic approaches to build out well architected solutions that go beyond immediate functionality encapsulated in a prompt.

Thirdly, as the article mentions, opportunity cost will never make this a favorable term - unless the SaaS vendor was extorting prices before. The direct cost of mental overhead and time of an internal team member to hand-hold an agent/ write specs/ debug/ firefight some LLM assisted/ vibe coded solution will not outweigh the upside potential of expanding your core business unless you're a stagnant enterprise product on life support.

by thenaturalist

Sensible people would do that (asking for just the features they need), but look at us, are we sensible?

Most of us* are working for places whose analytics software transitively asks the user for permission to be tracked by more "trusted" partners than the number of people in a typical high school, which transitively includes more bytes of code than the total size of DOOM including assets, with a performance hit so bad that it would be an improvement for everyone if the visitor remote desktop-ed into a VM running Win95 on the server.

And people were complaining about how wasteful software was when Win95 was new.

* Possibly an exaggeration, I don't know what business software is like; but websites and, in my experience at least, mobile apps do this.

I'm curious about your reasoning. Jira/Trello etc. are like $10/mo/seat, why bother rewriting them from scratch? You'll spend more in tokens doing so. Same for gmail/google calendar, what's the ROI? Those tools are reliable and cheap, why bother creating your own?

by levkk

2/21/2026 at 10:56:44 PM

jira/trello: ergonomics. to set them up correctly exactly the way i want would take me 20 hours (or hire a PM), i can vibecode for 20h and get the same result.

plus, being able to crossref internal data types is chef's kiss.

im paying for claude pro so it's use it or lose it. when i finish everything and have it battle tested i can end my claude code. and anyways when i have 10 employees, it's parity.

for gsuite: i want to own everything internally eventually ans having internal xrefs will be nice. the gsuite data is incidental, what is truly valuable about gsuite is spam detection and the oauth capability

Arguably it does, because being able to experience something gives you much more insight into whether it's right or not - so being able to iterate quickly many times, continuously updating your spec and definition of done should help you get to the right solution. To be clear, there is still effort involved, but the effort becomes more about the critical evaluation rather than the how.

by falcor84

2/21/2026 at 1:01:42 AM

But that's not the only problem.

To illustrate, I'll share what I'm working on now. My companies ops guy vibe coded a bunch of scripts to manage deployments. On the surface, they appear to do the correct thing. Except they don't. The tag for the Docker image used is hardcoded in a yaml file and doesn't get updated anywhere unless you do it manually. The docs don't even mention half of the necessary scripts/commands or implicit setup necessary for any of it to work in the first place, much less the tags or how any of it actually works. There are two completely different deployment strategies (direct to VM with docker + GCP and a GKE-based K8s deploy). Neither fully work, and only one has any documentation at all (and that documentation is completely vibed, so has very low information density). The only reason I'm able to use this pile of garbage at all is because I already know how all of the independent pieces function and can piece it together, but that's after wasting several hours of "why the fuck aren't my changes having an effect." There are very, very few lines of code that don't matter in well architected systems, but many that don't in vibed systems. We already have huge problems with overcomplicated crap made exclusively by humans, that's been hard enough to manage.

Vibe coding consistently gives the illusion of progress by fixing an immediate problem at the expense of piling on crap that obscures what's actually going on and often breaks exiting functionality. It's frankly not sustainable.

That being said, I've gotten some utility out of vibe coding tools, but it mostly just saves me some mental effort of writing boring shit that isn't interesting, innovative, or enjoyable, which is like 20% of mental effort and 5% of my actual work. I'm not even going to get started on the context switching costs. It makes my ADHD feel happy but I'm confident I'm less productive because of the secondary effects.

by packetlost

2/21/2026 at 4:22:18 AM

If you’re able to articulate the issues this clearly, it would take like an hour to “vibe code” away all of these issues. That’s the actual superpower we all have now. If you know what good software looks like, you can rough something out so fast, then iterate and clean it up equally fast, and produce something great an order of magnitude faster than just a few months ago.

A few times a week I’m finding open source projects that either have a bunch of old issues and pull requests, or unfinished todos/roadmaps, and just blasting through all of that and leaving a PR for the maintainer while I use the fork. All tested, all clean best practice style code.

Don’t complain about the outputs of these tools, use the tools to produce good outputs.

Devops is prime example of work to be minimized and ultimately eliminated entirely by automation. Yes, it's a complex domain rich in challenges and there's both art and skill to do it right, but at the same time, it's also not the thing we want, just the thing we have to do to get the thing we want, because we can't yet do better.

The post you’re r replying to gets this right- lead time is everything. The fast you can iterate, the more likely that what you are doing is correct.

Hilarious that you start with that as TAO requires

- Continuous adaptation makes it challenging to track performance changes and troubleshoot issues effectively.

- Advanced monitoring tools and sophisticated logging systems become essential to identify and address issues promptly.

- Adaptive models could inadvertently reinforce biases present in their initial training data or in ongoing feedback.

- Ethical oversight and regular audits are crucial to ensure fairness, transparency, and accountability.

Not much magic in there if it requires good old human oversight every step of the way, is there?

Of course it needs human supervision, see IBM 1979. Oversight however doesn’t mean the robots wait for approvals doing r&d and that’s where the magic is - the magic being robots overseeing their training and improvement of their harnesses.

Money is useful mostly for hiring human labor to outcompete others, e.g. Satya Nadella has 100K employees under his command, you don't, so you can't realistically compete with MS today - this is their main moat.

If AI renders human labor a cheap commodity (say you can orchestrate a bunch of agents to develop + market a Windows competitor for $1000 of compute), what used to be "Satya + his army vs. you" now becomes mostly a 1:1 fair fight, which favors the startup.

The buy vs build discussion has dramatically changed with GenAI. Some enterprise systems need to remain vendor based, but there’s a ton of space for mid-size and smaller companies to build and maintain their own systems and tons of software that were excel apps could be fully realized departmental systems.

by ChicagoDave

2/22/2026 at 9:31:56 AM

That's a short term view. Any system you build inhouse has to be maintained until you replace it, and often the longer it remains in place the harder it is to do that. You might save a small amount of cash (which might be important at the time tbf) but you're creating a major headache for later. Legacy code is debt, and that includes all your code. It's also a huge problem if the maintainer leaves because typically those small systems are owned by an individual dev who set it up in the first place.

Everyone who founds a company needs to remember that they're building a system of systems that all interact and influence each other, and you have to balance short term cash flow against long term strategy.

by onion2k

2/22/2026 at 3:19:36 PM

> It's also a huge problem if the maintainer leaves because typically those small systems are owned by an individual dev who set it up in the first place.

It's not uncommon that this maintainer actually wants to get away from maintaining this code, and would actually be quite willing to teach some successor how everything works.

The problem is that it is often hard to find someone who is similarly passionate about this system (often the system only keeps working because the original maintainer invests a lot of energy into keeping it alive), and is thus brutally willing to learn this system inside out. You can't force this mentality from above: either a suitable programmer has this mentality or he is typically not suitable.

Sorry, this take just shows that you probably are not running a business.

Let alone the maintenance, logistics, complexity, time etc. The economics just aren't there to vibe code even more than 30% of the software you use.

People running businesses want to focus on their core business and are happy to pay for pain points to go away, for money to come in or less money to come out. It's that simple.

by throw77488

2/23/2026 at 1:36:01 PM

If someone chooses the 1h free hack, sorry, you're doing business wrong and focus on the wrong things. A mindset that keeps you small. You gotta invest in stuff that makes you money and solves your problems. If that's what makes me sound like a salesman, again, I don't think you own a business as well or are struggling to make a living with that.

Theres a whole lot between "I waste my time and do non-scalable things" and "I need an enterprise contract as a SMB".

> Shitty python script with DuckDB running locally on laptop, can get you long long way.

Yeah ... no. You do you, but if you want to get your business to a good size you need proper tools. Like a chef needs a good knive, your business needs good tools as well. That's not to say that a quick DIY integration is off the table, but the one thing you don't get back is time, not money. So when you waste time by doing shit that can go away with minimal investment, you're preventing your business from getting traction.

Sorry but that's a coder mindset. "I can do this myself". That's what's keeping you stuck. You need to think about every decision as an investment. Time vs money. What's the ROI for all alternatives? Then you decide on what moves the needle. It's that easy.

The calculation is simple: every minute you do stupid stuff like coding shit, you can't sell to someone paying you to make things. So you lose twice by doing something yourself: a) you can't sell your services or time in the mean time and b) you add complexity and maintenance to your very complex business life as well. For me, the biggest problem is too much to do and not enough time. So to scale my business I need to reduce complexity. If I can throw reasonable money for that to go away: good, I'll do it. Most business owners I know think like that. That's business, not sales.

There are so many good SaaS for cheap or even with a good free tier that get you started that it's just incredibly junior to just build it yourself.

Why is it bad for AI to replace an enterprise software layer? Other than invalidating past investments.

by bhewes

2/21/2026 at 10:28:20 PM

A few reasons, "AI" as used by non-experts often has correctness and security issues. Even when it doesn't, its outputs are often not reproducible/predictable because they're probabilistic systems.

AI systems are also prone to writing code which they can't effectively refactor themselves, implying that many of these code bases are fiscal time bombs where human experts are required to come fix them. If the service being replaced has transactional behaviour, does the AI produced solution? Does the person using it know what that means?

The other side is that AI as an industry still needs to recoup trillions in investment, and enterprise users are potential whales for that.

Some of that latter part depends on how good and cheap open weight systems get. The ability to deploy your own will strictly limit the price of closed models if they aren't dominant in functionality.

a lot of low level ops stuff is going to be eaten up imo. half the bullshit you have to deal with is integrating data across every platform you are using or other supposed products to help you integrate the integrators lol. i guess if you're a huge company with 1000s of people this is an inherent problem anyway, one you can spend millions of dollars on.

it's not just "replace snowflake", there are a lot of times i wish i could build a very focused thing to accelerate some of our internal workflows and the nocode solutions either were too simplistic that you ended up spending just as much time trying to wrangle some generic solution to your own use case. OR it was not worth throwing significant engineering resources behind internal ops stuff. now that barrier is dropping fast and it's feasible for us.

whoever can create the framework/tooling for people build their own systems will win this, but i don't think it's something that can be "productized" like a saas.

I don't even know what this means, but my take: we should stop listening to VCs (especially those like A16Z) who have an obvious vested interest that doesn't match the rest of society. Granting these people an audience is totally unwarranted; nobody but other tech bros said "we will vibe code everything" in the first place. Best case scenario: they all go to the same exclusive conference, get the branded conference technical vest and that's were the asteroid hits.

I dunno.

I really hate the expression "the new normal", because it sort of smuggles in the assumption that there exists such thing as "normal". It always felt like one of those truisms that people say to exploit emotions like "in these trying times" or "no one wants to work anymore".

But I really do think that vibe coding is the "new normal". These tools are already extremely useful, to a point where I don't really think we'll be able to go back. These tools are getting good enough that it's getting to a point where you have to use them. This might sound like I'm supportive of this, and I guess am to some extent, but I find it to be exceedingly disappointing because writing software isn't fun anymore.

One of my most upvoted comments on HN talks about how I don't enjoy programming, but instead I enjoy problem solving. This was written before I was aware of vibe coding stuff, and I think I was wrong. I guess I actually did enjoy the process of writing the code, instead of just delegating my work to a virtual intern while I just watch the AI do the fun stuff.

A very small part of me is kind of hoping that once AI has to be priced at "not losing money on every call" levels that I'll be forced to actually think about this stuff again.

I have thought about this a lot, and I have no idea. I work for an "AI-first" company, and we're kind of required to use AI stuff as often as we can, so I make very liberal use of Codex, but I've been shielded from the interview process thus far.

I think I would still kind of ask the same questions, though maybe a bit more conceptual. Like, for example, I might see if I could get someone to explain how to build something, and then ask them about data structures that might be useful (e.g. removing a lock by making an append-only structure). I find that Codex will generally generate something that "works" but without an understanding data structures and algorithms, its implementation will still be somewhat sub-optimal, meaning that understanding the fundamentals has value, at least for now.

Let's just look at Dijkstra's On the Foolishness of "Natural Language Programming". It really does a good job at explaining why natural language programming (and thus, Vibe Coding) is a dead end. It serves as a good reminder that we developed the languages of Math and Programming for a reason. The pedantic nature is a feature, not a flaw. It is because in programming (and math) we are dealing with high levels of abstraction constantly and thus ambiguity compounds. Isn't this something we learn early on as programmers? That a computer does exactly what you tell it to, not what you intend to tell it to? Think about how that phrase extends when we incorporate LLM Coding Agents.

  | The virtue of formal texts is that their manipulations, in order to be legitimate, need to satisfy only a few simple rules; they are, when you come to think of it, an amazingly effective tool for ruling out all sorts of nonsense that, when we use our native tongues, are almost impossible to avoid.
  - Dijkstra

All of you have experienced the ambiguity and annoyances of natural language. Have you ever:

  - Had a boss give you confusing instructions?
  - Argued with someone only to find you agree?
  - Talked with someone and one of you doesn't actually understand the other?
    - Talked with someone and the other person seems batshit insane but they also seem to have avoided a mental asylum?
  - Use different words to describe the same thing?
    - When standing next to someone and looking at the same thing?
  - Adapted your message so you "talk to your audience"?
    - Ever read/wrote something on the internet? (where "everyone" is the audience)

Congrats, you have experienced the frustrations and limitations of natural language. Natural language is incredibly powerful and the ambiguity is a feature and a flaw, just like how in formal languages the precision is both a feature and a flaw. I mean it can take an incredible amount of work to say even very simple and obvious things with formal languages[1], but the ambiguity disappears[2].

Vibe Coding has its uses and I'm sure that'll expand, but the idea of it replacing domain experts is outright laughable. You can't get it to resolve ambiguity if you aren't aware of the ambiguity. If you've ever argued with the LLM take a step back and ask yourself, is there ambiguity? It'll help you resolve the problem and make you recognize the limits. I mean just look at the legal system, that is probably one of the most serious efforts to create formalization in natural language and we still need lawyers and judges to sit around and argue all day about all the ambiguity that remains.

I seriously can't comprehend how on a site who's primary users are programmers this is an argument. If we somehow missed this in our education (formal or self) then how do we not intuit it from our everyday interactions?

[2] Most programming languages are some hybrid variant. e.g. Python uses duck typing: if it looks like a float, operates like a float, and works as a float, then it is probably a float. Or another example even is C, what used to be called a "high level programming language" (so is Python a celestial language?). Give up some precision/lack of ambiguity for ease.

I don't think that's the argument. The argument I'm seeing most is that most of us SWEs will become obsolete once the agentic tools become good enough to allow domain experts to fully iterate on solutions on their own.

That’s been the argument since the 5PL movement in the 80s. What we discover is that domain expertise an articulation of domain expertise into systems are two orthogonal skills that occasionally develop in the same person but, in general, requires distinct specialization.

by shalmanese

2/21/2026 at 11:58:42 PM

It never worked because a lot of times, domain experts are stuck in their ways of doing things and the real innovation came from engineers learning from domain experts but adding their technically informed insights on the recipe to create novel ways of working.

A Lotus 1-2-3 vibecoded by a Product Manager in 1979 would probably had a hotkey for a calculator.

That is equivalent to "replacing domain experts", or at least was my intent. But language is ambiguous lol. I do think programmers are domain experts. There are also different kinds of domain experts but I very much doubt we'll get rid of SWEs.

Though my big concern right now is that we'll get rid of juniors and maybe even mid levels. There's definitely a push for that and incentives from an economic point of view. But it will be disastrous for the tech industry if this happens. It kills the pipeline. There can be no wizards without noobs. So we have a real life tragedy of the commons situation staring us in the face. I'm pretty sure we know what choices will be made, but I hope we can recognize that there's going to need to be cooperation to solve this least we all suffer.

by godelski

2/23/2026 at 8:33:03 PM

I know I'm shooting myself in the wallet here, but I honestly don't think that SWE is an "essential" domain. To explain, as one who has taken relational data modeling classes, it's obvious to me that everything that can be spoken about can be treated as a "domain", but if you'll allow me the terminology, I think that some are "essential", and others are "accidental".

I believe that business analysis and computer science are essential domains, of (respectively) properly defining the logical/mathematical constraints of problems, and of understanding what it means to solve such problems. But software engineering is "accidental", in the sense that no one other than us in the industry actually cares about what we do, but rather only about their use-cases implemented; what we do is just implementation details.

I don't have a magic ball, but I wouldn't be surprised if in a century, (human) software engineering goes the way of the switchboard operator, elevator operator or knocker-upper.

  > Dijkstra also said no one should be debugging

Given how you're implying things, you're grossly misrepresenting what he said. You've either been misled or misread. He was advocating for the adoption and development of provably correct programming.

Interestingly I think his "gospel" is only more meaningful today.

  | Apparently, many programmers derive the major part of their intellectual satisfaction and professional excitement from not quite understanding what they are doing. In this streamlined age, one of our most under-nourished psychological needs is the craving for Black Magic, and apparently the automatic computer can satisfy this need for the professional software engineers, who are secretly enthralled by the gigantic risks they take in their daring irresponsibility. They revel in the puzzles posed by the task of debugging. They defend —by appealing to all sorts of supposed Laws of Nature— the right of existence of their program bugs, because they are so attached to them: without the bugs, they feel, programming would no longer be what is used to be! (In the latter feeling I think —if I may say so— that they are quite correct.)

  | A program can be regarded as an (abstract) mechanism embodying as such the design of all computations that can possibly be evoked by it. How do we convince ourselves that this design is correct, i.e. that all these computations will display the desired properties? A naive answer to this question is "Well, try them all.", but this answer is too naive, because even for a simple program on the fastest machine such an experiment is apt to take millions of years. So, exhaustive testing is absolutely out of the question.

  | But as long as we regard the mechanism as a black box, testing is the only thing we can do. The unescapable conclusion is that we cannot afford to regard the mechanism as a black box

He literally said those exact words out loud from the audience during a job talk.

And yeah, the total aim and the reason why he might just blurt that out is because a lot of the frustration and esprit de corps of programming is held up in writing software that's more a guess about behavior than something provably correct. Perhaps we all ought to be writing provably correct software and never debugging as a result. We don't. But perhaps we ought to. We don't.

Is control via natural language a doomed effort? Perhaps, but I'd be cautious rather than confident about predicting that.

Forgive me for not believing you. I linked a source and you made speculations about what was in it. If you can't bother to read that then why should I believe you read anything else? Reading requires more than saying the words aloud in your head. At least if you want to read above a 3rd grade level.

We're basically in agreement, but you want to act like you're teaching me something. It's irritating.

One can fully understand that the goal is to write provable programs and yet we do not, we write programs that need debugging. So therefore, I don't think it's hard to imagine that if we get along with that, we may get along with natural language in the control channel, despite that being also proscribed in that vaunted essay you linked to me.

2) They named one of the two authors of the Fascist Manifesto their patron saint

3) AI systems are built to function in ways that degrade and are likely to destroy our crucial civic institutions. (Quoted from Professor Woodrow Hartzog "How AI Destroys Institutions"). Or to put it another way, being plausible but slightly wrong and un-auditable—at scale—is the killer feature of LLMs and this combination of properties makes it an essentially fascist technology meaning it is well suited to centralizing authority, eliminating checks on that authority and advancing an anti-science agenda (quoted from the A plausible, scalable and slightly wrong black box: why large language models are a fascist technology that cannot be redeemed post).

I will not claim to be an expert historian but one general belief I have is that nomenclature undergoes semantic migration over a century. So for the sake of conciseness I will quote the first demand of each portion of the Fascist Manifesto. This isn't to obscure, because it is in Wikipedia[0] and translated in English on EN Wikipedia[1], but so I can share a sample of whether this is something we can relate to our present day political orientation. Hopefully it will inform what you believe "author of the Fascist Manifesto" to imply:

> ...

> For this WE WANT:

> On the political problem:

> Universal suffrage by regional list voting, with proportional representation, voting and eligibility for women.

> ...

> On the social problem:

> WE WANT:

> The prompt enactment of a state law enshrining the legal eight-hour workday for all jobs.

> ...

> On the military issue:

> WE WANT:

> The establishment of a national militia with brief educational services and exclusively defensive duty.

> ...

> On the financial problem:

> WE WANT:

> A strong extraordinary tax on capital of a progressive nature, having the form of true PARTIAL EXPROPRIATION of all wealth.

Sure. They're making a strong claim, but I think they mean "author of the Fascist Manifesto" as shorthand to say Marinetti was an ardent supporter of fascism and Mussolini. His support continued throughout the 30's and 40's, even after the Pact of Steel and the Racial Laws etc, even volunteering to go to the Eastern Front. I think we can say with the benefit of hindsight that the fascists' attempts to ingratiate themselves to the worker's movement were sort of ancilliary to the whole political/ideological project... I mean I'd hope any student of history agrees with that...

by decidu0us9034

2/21/2026 at 5:15:22 AM

I’m not particularly political and am also not a historian but I don’t think it’s necessarily correct to equate the literal text of the manifesto with the principles and practices of fascism.

The message of universal suffrage vs. that of preventing an out group from “stealing” an election are not far apart semantically. Same with workers rights - in practice the worker protection laws that were passed in Italy at this time were so full of loopholes and qualifications that ultimately the workers do not gain power in that system.

It is this fair, in my view, to question the spirit of the manifesto in the first place.

Most SaaS companies are just expensive wrappers on top of existing tools. For non-VC-funded companies, SaaS tools are a serious cost. If you can re-create them in-house with AI, why wouldn't you? The result is saving capital (which you can then employ to do the more innovative things), and being in control over your own data.
