Auto-grading decade-old Hacker News discussions with hindsight

It's fun to read some of these historic comments! A while back I wrote a replay system to better capture how discussions evolved at the time of these historic threads. Here's Karpathy's list from his graded articles, in the replay visualizer:

Swift is Open Source https://hn.unlurker.com/replay?item=10669891

Launch of Figma, a collaborative interface design tool https://hn.unlurker.com/replay?item=10685407

I'd love to see sentiment analysis done based on time of day. I'm sure it's largely time zone differences, but I see a large variance in the types of opinions posted to hn in the morning versus the evening and I'd be curious to see it quantified.

by SauntSolaire

12/10/2025 at 11:16:28 PM

Yeah, I see this constantly any time Europe is mentioned in a submission. Early European morning/day, regular discussions, but as the European afternoon/evening comes around, you start noticing a lot anti-union sentiment, discussions start to shift into over-regulation, and the typical boring anti-Europe/EU talking points.

by embedding-shape

12/11/2025 at 2:41:46 AM

“Regular” to who? Pro EU sentiment almost only comes from the EU, which is what you’re observing. Pro-US sentiment is relatively mixed (as is anti-US sentiment) in distribution.

by nostrebored

12/11/2025 at 1:49:00 PM

> Pro EU sentiment almost only comes from the EU

Says who? But also, it doesn’t suggest what you imply. I could as easily conclude: “Oh wow, the people who actually experience the system like it that much? Awesome!”

by gilrain

12/12/2025 at 2:52:43 PM

Or one could conclude that the bots were posting at a time of day intending you as the reading target. As long as they post things that you are inclined to agree with, you'll feel positive reinforcement about an issue regardless of the actual popularity or even viability.

Comment dates on hn frontend are sometimes altered when submissions are merged, do you handle this case properly?

by arowthway

12/11/2025 at 3:04:53 PM

It is handled on the Unlurker front page (you will see a little note that says “time adjusted for second chance”). The replay doesn’t do any adjustment for it, but I think that makes it reflect the reality of when the comments came in since the adjustments are like a temporary bump

by jasonthorsness

I like the "past" functionality here, maybe wished there was one for week/month I could scroll back as well.

Miss it for reddit as well. Top day/week/month/alltime makes it hard to find top a month in 2018.

This is a cool idea. I would install a Chrome extension that shows a score by every username on this site grading how well their expressed opinions match what subsequently happened in reality, or the accuracy of any specific predictions they've made. Some people's opinions are closer to reality than others and it's not always correlated with upvotes.

An extension of this would be to grade people on the accuracy of the comments they upvote, and use that to weight their upvotes more in ranking. I would love to read a version of HN where the only upvotes that matter are from people who agree with opinions that turn out to be correct. Of course, only HN could implement this since upvotes are private.

by modeless

12/10/2025 at 7:51:24 PM

The RES (Reddit Enhancement Suite) browser extension indirectly does this for me since it tracks the lifetime number of upvotes I give other users. So when I stumble upon a thread with a user with like +40 I know "This is someone whom I've repeatedly found to have good takes" (depending on the context).

It's subjective of course but at least it's transparently so.

I just think it's neat that it's kinda sorta a loose proxy for what you're talking about but done in arguably the simplest way possible.

by cootsnuck

12/10/2025 at 8:17:36 PM

I am not a Redditor, but RES sounds like it would increase the ‘echo-chamber’ effect, rather than improving one’s understanding of contributors’ calibration.

by lukan

12/12/2025 at 12:56:37 AM

An echo chamber is a product of your own creation. If you're willing to upvote people who disagree with your and actively seek out opposite takes to be genuinely curious about, then you're probably not in an echo chamber.

The tools for controlling your feed are reducing on social media like Instagram, TikTok, Youtube, etc., but simply saying that you follow and respect the opinions of a select group doesn't necessarily mean you're forming an echo chamber.

This is different from something like flat earth/other conspiracy theories where when confronted with opposite evidence, they aren't likely to engage with it in good faith.

by xmprt

12/10/2025 at 8:22:31 PM

it depends on if you vote based on the quality of contribution to the discussion or based on how much you agree/disagree.

by mistercheph

12/11/2025 at 9:13:31 AM

I don't think you can change user behavior like this.

You can give them a "venting sink" though. Instead of having a downvote button that just downvotes, have it pop up a little menu asking for a downvote reason, with "spam" and "disagree" as options. You could then weigh downvotes by which option was selected, along with an algorithm to discover "user honesty" based on whether their downvotes correlate with others or just with the people on their end of the political spectrum, a la Birdwatch.

by miki123211

12/12/2025 at 4:03:02 AM

You can't change it for other users, only for yourself, which is what the original comment about the extension said.

by morshu9001

12/11/2025 at 8:45:59 AM

Echo chambers will always result on social media. I don't think you can come up with a format that will not result in consolidated blocs.

by intended

12/10/2025 at 8:36:42 PM

Reddit's current structure very much produces an echo chamber with only one main prevailing view. If everyone used an extension like this I would expect it to increase overall diversity of opinion on the site, as things that conflict with the main echo chamber view could still thrive in their own communities rather than getting downvoted with the actual spam.

by modeless

12/11/2025 at 7:39:44 PM

Hacker News structure is identical though. Topics invite different demographics and downvotes suppress unpopular opinions. The front page shows most up voted stories. It's the same system.

by XorNot

12/11/2025 at 9:06:34 PM

HN's moderation and ranking is better. But there's definitely an echo chamber effect here too.

by modeless

12/12/2025 at 4:03:45 AM

HN has some built-in ways to reduce this, like not allowing everyone to downvote everything.

by morshu9001

12/10/2025 at 8:38:07 PM

More than having exact same system but with any random reader voting ? I'd say as long as you don't do "I disagree therefore I downvote" it would probably be more accurate than having essentially same voting system driven by randoms like reddit/HN already does

by PunchyHamster

12/10/2025 at 9:43:03 PM

That assumes your upvotes in the past were a good proxy for being correct today. You could have both been wrong.

>This is a cool idea. I would install a Chrome extension that shows a score by every username on this site grading how well their expressed opinions match what subsequently happened in reality, or the accuracy of any specific predictions they've made.

Why stop there?

If you can do that you can score them on all sorts of things. You could make a "this person has no moral convictions and says whatever makes the number go up" score. Or some other kind of score.

Stuff like this makes the community "smaller" in a way. Like back in the old days on forums and IRC you knew who the jerks were.

That’s what Elon’s vision was before he ended up buying Twitter. Keep a digital track record for journalists. He wanted to call it Pravda.

(And we do have that in real life. Just as, among friends, we do keep track of who is in whose debt, we also keep a mental map of whose voice we listen to. Old school journalism still had that, where people would be reading someone’s column over the course of decades. On the internet, we don’t have that, or we have it rarely.)

by leobg

12/10/2025 at 8:21:15 PM

I long had a similar idea for stocks. Analyze posts of people giving stock tips on WSB, Twitter, etc and rank by accuracy. I would be very surprised if this had not been done a thousand times by various trading firms and enterprising individuals.

Of course in the above example of stocks there are clear predictions (HNWS will go up) and an oracle who resolves it (stock market). This seems to be a way harder problem for generic free form comments. Who resolves what prediction a particular comment has made and whether it actually happened?

by TrainedMonkey

12/11/2025 at 9:20:02 AM

> Analyze posts of people giving stock tips on WSB, Twitter, etc and rank by accuracy.

Didn't somebody make an ETF once that went against the prediction of some famous CNBC stock picker, showing that it would have given you alpha in the past.

> seems to be a way harder problem for generic free form comments.

That's what prediction markets are for. People for whom truth and accuracy matters (often concentrated around the rationalist community) will often very explicitly make annual lists of concrete and quantifiable predictions, and then self-grade on them later.

by miki123211

12/11/2025 at 6:55:37 PM

Cramer is the stock picker guy. There is a well known "Cramer Effect" or "Cramer Bounce" where the stock peaks then drops hard.

Makes for great pump n dump if you're day trading and willing to ride

https://www.investopedia.com/terms/c/cramerbounce.asp

long-term his choices don't do well, so the Inverse Cramer basically says "do the opposite of this goober" and has solid returns (sorta; depends a lot on methodology, and the sole hedgefund playing that strategy shutdown)

by mvkel

12/11/2025 at 9:21:10 AM

I like the idea and certainly would try it. Although I feel in a way this would be an anti-thesis to HN. HN tries to foster curiosity, but if you're (only) ranked by the accuracy of your predictions, this could give the incentive to always fall back to a save and boring position.

by emaro

12/14/2025 at 6:03:53 AM

I think the most interesting predictions are the ones that sound bold and even a little bit insane at the time. I think a lot more of the people who were willing to say saying "ASI will kill us all" 20+ years ago, because they were taking a risk (and routinely ridiculed for it).

Even today, "ASI will kill us all" can be a pretty divisive declaration - hardly safe and boring.

From the couple of threads I clicked, it seemed like this LLM-driven analysis was picking up on that, too: the top comments were usually bold, and some of the worst-rated comments was the "safe and boring" declaration that nothing interesting ever really happens.

by handoflixue

12/10/2025 at 8:51:44 PM

The problem seems underspecified; what does it mean for a comment to be accurate? It would seem that comments like "the sun will rise tomorrow" would rank highest, but they aren't surprising.

Didn't Slashdot have something like the second point with their meta-moderation, many many years ago?

by prawn

12/11/2025 at 8:05:05 PM

Sorta.

IIRC, when comment moderation and scoring came to Slashdot, only a random (and changing) selection of users were able to moderate.

Meta-moderation came a bit later. It allowed people to review prior moderation actions and evaluate the worth of those actions.

Those users who made good moderations were more likely to become a mod again in the future than those who made bad moderations.

The meta-mods had no idea whose actions they were evaluating, and previous/potential mods had no idea what their score was. That anonymity helped keep it honest and harder to game.

by ssl-3

12/14/2025 at 6:08:13 AM

It's still that way today: if you're active, you'll be randomly given 5 moderation points occasionally, and they expire after a few days. So you have to decide which threads and comments are worth spending a "moderation point" on

by handoflixue

12/14/2025 at 8:11:25 AM

How does meta-moderation work these days? I remember it being called Chips and Dip instead of /., but it's been many years since I've hung out there.

'pcwalton, I'm coming for you. You're going down.

Kidding aside, the comments it picks out for us are a little random. For instance, this was an A+ predictive thread (it appears to be rating threads and not individual comments):

https://news.ycombinator.com/item?id=10703512

But there's just 11 comments, only 1 for me, and it's like a 1-sentence comment.

I do love that my unaccredited-access-to-startup-shares take is on that leaderboard, though.

by tptacek

12/11/2025 at 5:12:10 AM

I noticed from reviewing my own entry (which honestly I'm surprised exists) that the idea of what it thinks constitutes a "prediction" is fairly open to interpretation, or at least that adding some nuance to a small aspect in a thread to someone else prediction counts quite heavily. I don't really view how I've participated here over the years in any way as making predictions. I actually thought I had done a fairly good job at not making predictions, by design.

by kbenson

12/11/2025 at 8:00:38 AM

Yeah, I'm having to pinch myself a little here. Another slightly odd example it picked out from your history: https://news.ycombinator.com/item?id=10735398

It's a good comment, but "prescient" isn't a word I'd apply to it. This is more like a list of solid takes. To be fair there probably aren't even that many explicit, correct predictions in one month of comments in 2015.

I've spent a weekend making something similar for my gmail account (which google keeps nagging me about being 90% full). It's fascinating to be able to classify 65k+ of emails (surprise: more than half are garbage), as well as summarize and trace the nature of communication between specific senders/recipients. It took about 50 hours on a dual RTX 3090 running Qwen 3.

My original goal was to prune the account deleting all the useless things and keeping just the unique, personal, valuable communications -- but the other day, an insight has me convinced that the safer / smarter thing to do in the current landscape is the opposite: remove any personal, valuable, memorable items, and leave google (and whomever else is scraping these repositories) with useless flotsam of newsletters, updates, subscription receipts, etc.

by btbuildem

12/11/2025 at 7:13:52 PM

I would love to do something like this, and weirdly I even have a dual 3090 home setup.

Any chance you can outline the steps/prompts/tools you used to run this?

12/10/2025 at 8:26:59 PM

One thing this really highlights to me is how often the "boring" takes end up being the most accurate. The provocative, high-energy threads are usually the ones that age the worst.

If an LLM were acting as a kind of historian revisiting today’s debates with future context, I’d bet it would see the same pattern again and again: the sober, incremental claims quietly hold up, while the hyperconfident ones collapse.

Something like "Lithium-ion battery pack prices fall to $108/kWh" is classic cost-curve progress. Boring, steady, and historically extremely reliable over long horizons. Probably one of the most likely headlines today to age correctly, even if it gets little attention.

On the flip side, stuff like "New benchmark shows top LLMs struggle in real mental health care" feels like high-risk framing. Benchmarks rotate constantly, and “struggle” headlines almost always age badly as models jump whole generations.

I bet theres many "boring but right" takes we overlook today and I wondr if there's a practical way to surface them before hindsight does

by Rperry2174

12/10/2025 at 8:47:40 PM

"Boring but right" generally means that this prediction is already priced in to our current understanding of the world though. Anyone can reliably predict "the sun will rise tomorrow", but I'm not giving them high marks for that.

by yunwal

12/10/2025 at 9:04:59 PM

I'm giving them higher marks than the people who say it won't.

LLMs have seen huge improvements over the last 3 years. Are you going to make the bet that they will continue to make similarly huge improvements, taking them well past human ability, or do you think they'll plateau?

The former is the boring, linear prediction.

by onraglanroad

12/10/2025 at 11:05:23 PM

>The former is the boring, linear prediction.

right, because if there is one thing that history shows us again and again is that things that have a period of huge improvements never plateau but instead continue improving to infinity.

Improvement to infinity, that is the sober and wise bet!

by bryanrasmussen

12/11/2025 at 12:56:07 AM

The prediction that a new technology that is being heavily researched plateaus after just 5 years of development is certainly a daring one. I can’t think of an example from history where that happened.

Perhaps the fact that you think this field is only 5 years old means you're probably not enough of an authority to comment confidently on it?

by OccamsMirror

12/11/2025 at 5:01:44 AM

Claiming that AI in anything resembling its current form is older than 5 years is like claiming the history of the combustion engine started when an ape picked up a burning stick.

by p-e-w

12/11/2025 at 8:20:29 AM

Your analogy fails because picking up a burning stick isn’t a combustion engine, whereas decades of neural-net and sequence-model work directly enabled modern LLMs. LLMs aren’t “five years old”; the scaling-transformer regime is. The components are old, the emergent-capability configuration is new.

Treating the age of the lineage as evidence of future growth is equivocation across paradigms. Technologies plateau when their governing paradigm saturates, not when the calendar says they should continue. Supersonic flight stalled immediately, fusion has stalled for seventy years, and neither cared about “time invested.”

Early exponential curves routinely flatten: solar cells, battery density, CPU clocks, hard-disk areal density. The only question that matters is whether this paradigm shows signs of saturation, not how long it has existed.

You don't think humans hunted tigers in 40,000BC?

by OccamsMirror

12/13/2025 at 12:36:46 AM

I don't think it would make much sense to hunt large predators prior to the invention of agriculture, even though early humans were probably plenty smart enough to build traps capable of holding animals like tigers. But after that (less than 40k years ago, more than 10k years ago), I'd bet it was a common-ish thing for humans to try to hunt predators that preyed upon their livestock.

Tigers are terrifying, though. I think it takes extreme or perverse circumstances to make hunting a tiger make any sense at all. And even then, traps and poisons make more sense than stalking a tiger to kill it!

You joke, but, alas, there is a _real_ company kinda trying to do this. Reflect Orbital[1] wants to set up space mirrors, so you can have daytime at night for your solar panels! (Various issues, like around light pollution and the fact that looking up at the proposed satellites with binoculars could cause eye damage... don't seem to be on their roadmap.) This is one idea that's going to age badly whether or not they actually launch anything, I suspect.

Battery tech is too boring, but seems more likely to manage long-term effectiveness.

by yunwal

12/10/2025 at 9:23:54 PM

“At what?” is really the key question here.

A lot of the press likes to paint “AI” as a uniform field that continues to improve together. But really it’s a bunch of related subfields. Once in a blue moon a technique from one subfield crosses over into another.

“AI” can play chess at superhuman skill. “AI” can also drive a car. That doesn’t mean Waymo gets safer when we increase Stockfish’s elo by 10 points.

I imagine "better" in this case depends on how one scores "I don't know" or confident-sounding falsehoods.

by Terr_

At every intellectual task.

They're already better than you at reciting historical facts. I'd guess they're probably better at composing poems (they're not great but far better than the average person).

Or you agree with me? I'm not looking for prescience marks, I'm just less convinced that people really make the more boring and obvious predictions.

by onraglanroad

12/10/2025 at 9:26:10 PM

What is an intellectual task? Once again, there's tons of stuff LLMs won't be trained on in the next 3 years. So it would be trivial to just find one of those things and say voila! LLMs aren't better than me at that.

I'll make one prediction that I think will hold up. No LLM-based system will be able to take a generic ask like "hack the nytimes website and retrieve emails and password hashes of all user accounts" and do better than the best hackers and penetration testers in the world, despite having plenty of training data to go off of. It requires out-of-band thinking that they just don't possess.

by yunwal

12/10/2025 at 9:55:12 PM

I'll take a stab at this: LLMs currently seem to be rather good at details, but they seem to struggle greatly with the overall picture, in every subject.

- If I want Claude Code to write some specific code, it often handles the task admirably, but if I'm not sure what should be written, consulting Claude takes a lot of time and doesn't yield much insight, where as 2 minutes with a human is 100x more valuable.

- I asked ChatGPT about some political event. It mirrored the mainstream press. After I reminded it of some obvious facts that revealed a mainstream bias, it agreed with me that its initial answer was wrong.

These experiences and others serve to remind me that current LLMs are mostly just advanced search engines. They work especially well on code because there is a lot of reasonably good code (and tutorials) out there to train on. LLMs are a lot less effective on intellectual tasks that humans haven't already written and published about.

To be clear, you are suggesting “huge improvements” in “every intellectual task”?

This is unlikely for the trivial reason that some tasks are roughly saturated. Modest improvements in chess playing ability are likely. Huge improvements probably not. Even more so for arithmetic. We pretty much have that handled.

But the more substantive issue is that intellectual tasks are not all interconnected. Getting significantly better at drawing hands doesn’t usually translate to executive planning or information retrieval.

> They're already better than you at reciting historical facts.

They're better at regurgitating historical facts than me because they were trained on historical facts written by many humans other than me who knew a lot more historical facts. None of those facts came from an LLM. Every historical fact that isn't entirely LLM generated nonsense came from a human. It's the humans that were intelligent, not the fancy autocomplete.

Now that LLMs have consumed the bulk of humanity's written knowledge on history what's left for it to suck up will be mainly its own slop. Exactly because LLMs are not even a little bit intelligent they will regurgitate that slop with exactly as much ignorance as to what any of it means as when it was human generated facts, and they'll still spew it back out with all the confidence they've been programed to emulate. I predict that the resulting output will increasingly shatter the illusion of intelligence you've so thoroughly fallen for so far.

by OrderlyTiamat

12/10/2025 at 11:33:53 PM

LLMs aren't getting better that fast. I think a linear prediction says they'd need quite a while to maybe get "well past human ability", and if you incorporate the increases in training difficulty the timescale stretches wide.

Prediction markets have pretty much obviated the need for these things. Rather than rely on "was that really a hot take?" you have a market system that rewards those with accurate hot takes. The massive fees and lock-up period discourage low-return bets.

The one about LLMs and mental health is not a prediction but a current news report, the way you phrased it.

Also, the boring consistent progress case for AI plays out in the end of humans as viable economic agents requiring a complete reordering of our economic and political systems in the near future. So the “boring but right” prediction today is completely terrifying.

by jimbokun

12/11/2025 at 12:53:46 AM

“Boring” predictions usually state that things will continue to work the way they do right now. Which is trivially correct, except in cases where it catastrophically isn’t.

So the correctness of boring predictions is unsurprising, but also quite useless, because predicting the future is precisely about predicting those events which don’t follow that pattern.

by schoen

12/10/2025 at 9:37:11 PM

This suggests that the best way to grade predictions is some sort of weighting of how unlikely they were at the time. Like, if you were to open a prediction market for statement X, some sort of grade of the delta between your confidence of the event and the “expected” value, summed over all your predictions.

by johnfn

12/10/2025 at 9:48:26 PM

Exactly, that's the element that is missing. If there are 50 comments against and one pro and that pro has it in the longer term then that is worth noticing, not when there are 50 comments pro and you were one of the 'pros'.

Going against the grain and turning out right is far more valuable than being right consistently when the crowd is with you already.

by jacquesm

12/11/2025 at 6:31:14 AM

Would the commenter above mind sharing the method behind of their generalization? Many people would spot check maybe five items -- which is enough for our brains to start to guess at potential patterns -- and stop there.

On HN, when I see a generalization, one of my mental checklist items is to ask "what is this generalization based on?" and "If I were to look at the problem with fresh eyes, what would I conclude?".

A majority don't seem to be predictions about the future, and it seems to mostly like comments that give extended air to what was then and now the consensus viewpoint, e.g. the top comment from pcwalton the highest scored user: https://news.ycombinator.com/item?id=10657401

> (Copying my comment here from Reddit /r/rust:) Just to repeat, because this was somewhat buried in the article: Servo is now a multiprocess browser, using the gaol crate for sandboxing. This adds (a) an extra layer of defense against remote code execution vulnerabilities beyond that which the Rust safety features provide; (b) a safety net in case Servo code is tricked into performing insecure actions. There are still plenty of bugs to shake out, but this is a major milestone in the project.

I noticed the Hall of Fame grading of predictive comments has a quirk? It grades some comments about if they came true or not, but in the grading of comment to the article

https://news.ycombinator.com/item?id=10654216

The Cannons on the B-29 Bomber "accurate account of LeMay stripping turrets and shifting to incendiary area bombing; matches mainstream history"

It gave a good grade to user cstross but to my reading of the comment, cstross just recounted a bit of old history. The evaluation gave cstross for just giving a history lesson or no?

by hackthemack

12/10/2025 at 7:44:07 PM

Yes I noticed a few of these around. The LLM is a little too willing to give out grades for comments that were good/bad in a bit more general sense, even if they weren't making strong predictions specifically. Another thing I noticed is that the LLM has a very impressive recognition of the various usernames and who they belong to, and I think shows a little bit of a bias in its evaluations based on the identity of the person. I tuned the prompt a little bit based on some low-hanging fruit mistakes but I think one can most likely iterate it quite a bit further.

by pierrec

12/10/2025 at 9:14:32 PM

I am surprised the author thought the project passed quality control. The LLM reviews seem mostly false.

Looking at the comment reviews on the actual website, the LLM seems to have mostly judged whether it agreed with the takes, not whether they came true, and it seems to have an incredibly poor grasp of it's actual task of accessing whether the comments were predictive or not.

The LLM's comment reviews are of often statements like "correctly characterized [program language] as [opinion]."

This dynamic means the website mostly grades people on having the most confirmist take (the take most likely to dominate the training data, and be selected for in the LLM RL tuning process of pleasing the average user).

by LeroyRaz

12/10/2025 at 9:28:54 PM

Examples: tptacek gets an 'A' for his comment on DF which the LLM claiming that the user "captured DF's unforgiving nature, where 'can't do x or it crashes is just another feature to learn' which remained true until it was fixed on ..."

Link to LLM review: https://karpathy.ai/hncapsule/2015-12-02/index.html#article-....

So the LLM is praising a comment as describing DF as unforgiving (a characterization of the present then, not a statement about the future). And worse, it seems like tptacek may in fact be implying the opposite of the future (e.g., x will continue to crash when it was eventually fixed.)

Here is the original comment: " tptacek on Dec 2, 2015 | root | parent | next [–]

If you're not the kind of person who can take flaws like crashes or game-stopping frame-rate issues and work them into your gameplay, DF is not the game for you. It isn't a friendly game. It can take hours just to figure out how to do core game tasks. "Don't do this thing that crashes the game" is just another task to learn."

Note: I am paraphrasing the LLM review, as the website is also poorly designed, with one unable to select the text of the LLM review!

N.b., this choice of comment review is not overly cherry picked. I just scanned the "best commentators" and tptacek was number two, with this particular egregiously unrelated-to-prediction LLM summary given as justifying his #2 rating.

by LeroyRaz

12/10/2025 at 9:28:36 PM

Are you sure? The third section of each review lists the “Most prescient” and “Most wrong” comments. That sounds exactly like what you're looking for. For example, on the "Kickstarter is Debt" article, here is the LLM's analysis of the most prescient comment. The analysis seems accurate and helpful to me.

https://karpathy.ai/hncapsule/2015-12-03/index.html#article-...

  phire

  > “Oculus might end up being the most successful product/company to be kickstarted… > Product wise, Pebble is the most successful so far… Right now they are up to major version 4 of their product. Long term, I don't think they will be more successful than Oculus.”

  With hindsight:

  Oculus became the backbone of Meta’s VR push, spawning the Rift/Quest series and a multi‑billion‑dollar strategic bet.
  Pebble, despite early success, was shut down and absorbed by Fitbit barely a year after this thread.

  That’s an excellent call on the relative trajectories of the two flagship Kickstarter hardware companies.

Until someone publishes a systematic quality assessment, we're grasping at anecdotes.

It is unfortunate that the questions of "how well did the LLM do?" and "how does 'grading' work in this app?" seem to have gone out the window when HN readers see something shiny.

by xpe

12/11/2025 at 2:48:36 AM

Yes. And the article is a perfect example of the dangerous sort of automation bias that people will increasingly slide into when it comes to LLMs. I realize Karpathy is sort of incentivized toward this bias given his career, but he doesn't even spend a single sentence even so much as suggesting that the results would need further inspection, or that they might be inaccurate.

The LLM is consulted like a perfect oracle, flawless in its ability to perform a task, and it's left at that. Its results are presented totally uncritically.

For this project, of course, the stakes are nil. But how long until this unfounded trust in LLMs works its way into high stakes problems? The reign of deterministic machines for the past few centuries has ingrained a trust in the reliability of machines in us that should be suspended when dealing with an inherently stochastic device like an LLM.

by voidhorse

12/11/2025 at 1:04:57 AM

I get what you're saying, but looking at some examples, they look kinda of right, but there are a lot of misleading facts sprinkled, making his grading wrong. It is useful, but I'd suggest to be careful to use this to make decisions.

Some of the issues could be resolved with better prompting (it was biased to always interpret every comment through the lens of predictions) and LLM-as-a-judge, but still. For example, Anthropic's Deep Research prompts sub-agents to pass original quotes instead of paraphrasing, because it can deteriorate the original message.

Some examples:

  Swift is Open Source (2015)
  ===========================
sebastiank123 got a C-, and was quoted by the LLM as saying:

  > “It could become a serious Javascript competitor due to its elegant syntax, the type safety and speed.”
Now, let's read his full comment:

  > Great news! Coding in Swift is fantastic and I would love to see it coming to more platforms, maybe even on servers. It could become a serious Javascript competitor due to its elegant syntax, the type safety and speed.
I don't interpret it as a prediction, but a desire. The user is praising Swift. If it went the server way, perhaps it could replace JS, to the user's wishes. To make it even clearer, if someone asked the commenter right after: "Is that a prediction? Are you saying Swift is going to become a serious Javascript competitor?" I don't think its answer would be 'yes' in this context.

  How to be like Steve Ballmer (2015)
  ===================================
  
  Most wrong
  ----------
  
  >     corford (grade: D) (defending Ballmer’s iPhone prediction):
  >         Cited an IDC snapshot (Android 79%, iOS 14%) and suggested Ballmer was “kind of right” that the iPhone wouldn’t gain significant share.
  >         In 2025, iOS is one half of a global duopoly, dominates profits and premium segments, and is often majority share in key markets. Any reasonable definition of “significant” is satisfied, so Ballmer’s original claim—and this defense of it—did not age well.
Full quote:

  > And in a funny sort of way he was kind of right :) http://www.forbes.com/sites/dougolenick/2015/05/27/apple-ios...
  > Android: 79% versus iOS: 14%
"Any reasonable definition of 'significant' is satisfied"? That's not how I would interpret this. We see it clearly as a duopoly in North America. It's not wrong per se, but I'd say misleading. I know we could take this argument and see other slices of the data (premium phones worldwide, for instance), I'm just saying it's not as clear cut as it made it out to be.

  > volandovengo (grade: C+) (ill-equipped to deal with Apple/Google):
  >  
  >     Wrote that Ballmer’s fast-follower strategy “worked great” when competitors were weak but left Microsoft ill-equipped for “good ones like Apple and Google.”
  >     This is half-true: in smartphones, yes. But in cloud, office suites, collaboration, and enterprise SaaS, Microsoft became a primary, often leading competitor to both Apple and Google. The blanket claim underestimates Microsoft’s ability to adapt outside of mobile OS.
That's not what the user was saying:

  > Despite his public perception, he's incredibly intelligent. He has an IQ of 150.
  > 
  > His strategy of being a fast follower worked great for Microsoft when it had crappy competitors - it was ill equipped to deal with good ones like Apple and Google.
He was praising him and he did miss opportunities at first. OC did not make predictions of his later days.

  [Let's Encrypt] Entering Public Beta (2015)
  ===========================================

  - niutech: F "(endorsed StartSSL and WoSign as free options; both were later distrusted and effectively removed from the trusted ecosystem)"
Full quote:

  > There are also StartSSL and WoSign, which provide the A+ certificates for free (see example WoSign domain audit: https://www.ssllabs.com/ssltest/analyze.html?d=checkmyping.c...)
  > 
  > pjbrunet: F (dismissed HTTPS-by-default arguments as paranoid, incorrectly asserted ISPs had stopped injection, and underestimated exactly the use cases that later moved to HTTPS)
Full quote:

  > "We want to see HTTPS become the default."
  > 
  > Sounds fine for shopping, online banking, user authorizations. But for every website? If I'm a blogger/publisher or have a brochure type of website, I don't see point of the extra overhead.
  > 
  > Update: Thanks to those who answered my question. You pointed out some things I hadn't considered. Blocking the injection of invisible trackers and javascripts and ads, if that's what this is about for websites without user logins, then it would help to explicitly spell that out in marketing communications to promote adoption of this technology. The free speech angle argument is not as compelling to me though, but that's just my opinion.
I thought the debate was useful and so did pjbrunet, per his update.

I mean, we could go on, there are many others like these.

I haven’t looked at the output yet, but came here to say,LLM grading is crap. They miss things, they ignore instructions, bring in their own views, have no calibration and in general are extremely poorly suited to this task. “Good” LLM as a judge type products (and none are great) use LLMs to make binary decisions - “do these atomic facts match yes / no” type stuff - and aggregate them to get a score.

I understand this is just a fun exercise so it’s basically what LLMs are good at - generating plausible sounding stuff without regard for correctness. I would not extrapolate this to their utility on real evaluation tasks.

Predictions are only valuable when they're actually made ahead of the knowledge becoming available. A man will walk on mars by 2030 is falsifiable, a man will walk on mars is not. A lot of these entries have very low to no predictive value or were already known at the time, but just related. Would be nice if future 'judges' put in more work to ensure quality judgments.

It would be very interesting to see this applied year after year to see if people get better or worse over time in the accuracy of their judgments.

It would also be interesting to correlate accuracy to scores, but I kind of doubt that can be done. Between just expressing popular sentiment and the first to the post people getting more votes for the same comment than people who come later it probably wouldn’t be very useful data.

Many people are impressed by this, and I can see why. Still, this much isn't surprising: the Karpathy + LLM combo can deliver quickly. But there are downsides of blazing speed.

If you dig in, there are substantial flaws in the project's analysis and framing, such as the definition of a prediction, assessing comments, data quality overall, and more. Go spelunking through the comments here and notice people asking about methodology and checking the results.

Social science research isn't easy; it requires training, effort, and patience. I would be very happy if Karpathy added a Big Flashing Red Sign to this effect. It would raise awareness and focus community attention on what I think are the hardest and most important aspects of this kind of project: methodology, rigor, criticism, feedback, and correction.

Okay, but the only part that’s specific to AI (that the companies investing the money are capturing more value than they’re putting into it) is now false. Even the hyperscalers are not capturing nearly the value they’re investing, though they’re not using debt to finance it. OpenAI and Anthropic are of course blowing through cash like it’s going out of style, and if investor interest drops drastically they’ll likely need to look to get acquired.

It's a shame that maintaining the web is so hard that only a few websites are "good citizens". I wish the web was a -bit- way more like git. It should be easier to crawl the web and serve it.

Say, you browse and get things cached and shared, but only your "local bookmarks" persist. I guess it's like pinning in IPFS.

by dietr1ch

Yes, I wish we could serve static content more like bittorent, where your uri has an associate hash, and any intermediate router or cache could be an equivalent source of truth, with the final server only needing to play a role if nothing else has it.

It is not possible right now to make hosting democratized/distributed/robust because there's no way for people to donate their own resources in a seamless way to keeping things published. In an ideal world, the internet archive seamlessly drops in to serve any content that goes down in a fashion transparent to the user.

I think that many are able to toss a almost permanently online raspberry pi in their homes and that's probably enough for sustaining a decently good distributed CAS network that shares small text files.

I suppose they want to make the comments seem "fresh" but it's a deliberate misrepresentation. You could probably even contrive a situation where it could be damaging, e.g. somebody says something before some relevant incident, but the website claims they said it afterwards.

by Y_Y

12/10/2025 at 10:42:26 PM

I think the reason is much simpler than that. Resetting the timestamp lets them easily resurface things on the frontpage, because the current time - posting time delta becomes a lot smaller, so it's again ranked higher. And avoiding adding a special case, lets the rest of the codebase work exactly like it was before, basically just need to add a "set submission time to now" function and you get the rest for free.

But, I'm just guessing here based on my own refactoring experience through the years, may be a completely different reason, or even by mistake? Who knows? :)

There is some action that moderators can take that throws one of yesterday's articles back on the front page and when that happens all the comments have the same timestamp.

I appreciate your intent, but this tool needs a lot of work -- maybe an entire redesign -- before it would be suitable for the purpose you seek. See discussion at [1].

Besides, in my experience, only a tiny fraction of HN comments can be interpreted as falsifiable predictions.

Instead I would recommend learning about calibration [2] and ways to improve one's calibration, which will likely lead you into literature reviews of cognitive biases and what we can do about them. Also, jumping into some prediction markets (as long as they don't become too much of a distraction) is good practice.

That is interesting because of the Halo effect. There is a cognitive bias that if a person is right in one area, they will be right in another unrelated area.

I try to temper my tendency to believe the Halo effect with Warren Buffett's notion of the Circle of Competence; there is often a very narrow domain where any person can be significantly knowledgeable.

by brian_spiering

12/14/2025 at 12:33:10 AM

> A circle of competence is the subject area which matches a person's skills or expertise. The concept was developed by Warren Buffett and Charlie Munger as what they call a mental model, a codified form of business acumen, concerning the investment strategy of limiting one's financial investments in areas where an individual may have limited understanding or experience, while concentrating in areas where one has the greatest familiarity. -Wikipedia

> I try to temper my tendency to believe the Halo effect with Warren Buffett's notion of the Circle of Competence; there is often a very narrow domain where any person can be significantly knowledgeable. (commenter above)

Putting aside Buffett in particular, I'm wary of claims like "there is often a very narrow domain where any person can be significantly knowledgeable". How often? How narrow of a domain? Doesn't it depend on arbitrary definitions of what qualifies as a category? Is this a testable theory? Is it a predictive theory? What does empirical research and careful analysis show?

Putting that aside, there are useful mathematical ways to get an idea of some of the backing concepts without making assumptions about people, culture, education, etc. I'll cook one up now...

Start with 70K balls split evenly across seven colors: red, orange, yellow, green, blue, indigo, and violet. 1,000 show up demanding balls. So we mix them up and randomly distribute 10 balls to every person. What does the distribution tend to look like? What particulars would you tune and/or definitions would you choose to make this problem "sort of" map to something sort of like assessing the diversity of human competence across different areas?

Note the colored balls example assumes independence between colors (subjects or skills or something). But in real life, there are often causally significant links between skills. For example, general reasoning ability improves performance in a lot of other subjects.

Then a goat exploded, because I don't know how to end this comment gracefully.

by HighGoldstein

12/11/2025 at 4:43:08 AM

It doesn't look like the code anonymizes usernames when sending the thread for grading. This likely induces bias in the grades based on past/current prevailing opinions of certain users. It would be interesting to see the whole thing done again but this time randomly re-assigning usernames, to assess bias, and also with procedurally generated pseudonyms, to see whether the bias can be removed that way.

I'd expect de-biasing would deflate grades for well known users.

It might also be interesting to use a search-grounded model that provides citations for its grading claims. Gemini models have access to this via their API, for example.

A further question is whether a bespoke username could influence the bias of a particular comment (e.g. A username of something like HatesPython might influence the interpretation of that commenter's particular perception of the Python coding language, which might actually be expressing positivity — the username's irony lost to the AI?).

by strken

12/11/2025 at 5:11:07 PM

This doesn't even seem to look at "predictions" if you dig into what it actually did. Looking at my own example (#210 on https://karpathy.ai/hncapsule/hall-of-fame.html with 4 comments), very little of what I said could be construed as "predictions" at all.

I got an A for commenting on DF saying that I had not personally seen save corruption and listing weird bugs. It's true that weird bugs have long been a defining feature of DF, but I didn't predict it would remain that way or say that save corruption would never be a big thing, just that I hadn't personally seen it.

Another A for a comment on Google wallet just pointing out that users are already bad at knowing what links to trust. Sure, that's still true (and probably will remain true until something fundamental changes), but it was at best half a prediction as it wasn't forward looking.

Then something on hospital airships from the 1930s. I pointed out that one could escape pollution, I never said I thought it would be a big thing. Airships haven't really ever been much of a thing, except in fiction. Maybe that could change someday, but I kinda doubt it.

Then lastly there was the design patent famously referred to as the "rounded corner" patent. It dings me for simplifying it to that label, despite my actual statements being that yes, there's more, but just minor details like that can be sufficient for infringement. But the LLM says I'm right about ties to the Samsung case and still oversimplifying it. Either way, none of this was really a prediction to begin with.

by koakuma-chan

12/10/2025 at 8:30:19 PM

I understand the exercise, but I think it should have a disclaimer, some of the LLM reviews are showing a bias and when I read the comments they turned out not to be as bad as the LLM made them. As this hits the front page, some people will only read the title and not the accompanying blog post, losing all of the nuance.

That said, I understand the concept and love what you did here. By this being exposed to the best disinfectant, I hope it will raise awareness and show how people and corporations should be careful about its usage. Now this tech is accessible to anyone, not only big techs, in a couple of hours.

It also shows how we should take with a grain of salt the result of any analysis of such scale by a LLM. Our private channels now and messages on software like Teams and Slack can be analyzed to hell by our AI overlords. I'm probably going to remove a lot of things from cloud drives just in case. Perhaps online discourse will deteriorate to more inane / LinkedIn style content.

Also, I like that your prompt itself has some purposefully leaked bias, which shows other risks—¹for instance, "fsflover: F", which may align the LLM to grade worse the handles that are related to free software and open source).

As a meta concept of this, I wonder how I'll be graded by our AI overlords in the future now that I have posted something dismissive of it.

What's interesting is that the hindsight it has now is not going to be what it has in 10 years either. Some of the most wrong and most prescient comments could switch as stuff unfolds. In a way some could both still be wrong and right just at different points in time.

by abhinav_sk

12/10/2025 at 8:49:31 PM

Looking at the results and the prompt, I would tweak the prompt to

* ignore comments that do not speculate on something that was unknown or had not achieved consensus as of the date of yyyy-mm-dd

* at the same time, exclude speculations for which there still isn’t a definitive answer or consensus today

* ignore comments that speculate on minor details or are stating a preference/opinion on a subjective matter

* it is ok to generate an empty list of users for a thread if there are no comments meeting the speculation requirements laid out above

* etc

Agreed. I feel like it's more just a collection of good comments. It doesn't surprise me to see tptacek, patio11, etc there. I think the "prediction" aspect is under weighted.

But it reminds me that I miss Manishearth's comments! What ever happened to him? I recall him being a big rust contributor. I'd think he'd be all over the place, with rust's adoption since then. I also liked tokenadult. interesting blast from the past.

I have never felt less confident in the future than I do in 2025... and it's such a stark contrast. I guess if you split things down the middle, AI probably continues to change the world in dramatic ways but not in the all or nothing way people expect.

A non trivial amount of people get laid off, likely due to a finanical crisis which is used as an excuse for companies scale up use of AI. Good chance the financial crisis was partly caused by AI companies, which ironically makes AI cheaper as infra is bought up on the cheap (so there is a consolidation, but the bountiful infra keeps things cheap). That results in increased usage (over a longer period of time). and even when the economy starts coming back the jobs numbers stay abismal.

Politics are divided into 2 main groups, those who are employed, and those who are retired. The retired group is VERY large, and has alot of power. They mostly care about entitlements. The employed age people focus on AI which is making the job market quite tough. There are 3 large political forces (but 2 parties). The Left, the Right, and the Tech Elite. The left and the right both hate AI, but the tech elite though a minority has outsized power in their tie breaker role. The age distributions would surprise most. Most older people are now on the left, and most younger people are split by gender. The right focuses on limiting entitlements, and the left focuses on growing them by taxing the tech elite. The right maintains power by not threatening the tech elite.

Unlike the 20th century America is a more focused global agenda. We're not policing everyone, just those core trading powers. We have not gone to war with China, China has not taken over Taiwan.

Physical robotics is becoming a pretty big thing, space travel is becoming cheaper. We have at least one robot on an astroid mining it. The yield is trivial, but we all thought it was neat.

Energy is much much greener, and you wouln't have guessed it... but it was the data centers that got us there. The Tech elite needed it quickly, and used the political connections to cut red tape and build really quickly.

We do not currently have the political apparatus in place to stop the dystopian nightmares depicted in movies and media. They were supposed to be cautionary tales.

No, and I'm not sure why you are asking me this. Superforecasters does not make that claim.

I've found the opposite, since these models still fail pretty wildly at nuance. I think it's a conceptual "needle in the haystack sort of problem.

A good test is to find some thread where there's a disagreement and have it try to analyze the discussion. It will usually strongly misrepresent what was being said, by each side, and strongly align with one user, missing the actual divide that's causing the disagreement (a needle).

That will most definitely happen. We already have known for awhile that algorithmic methods have been applied "to products and initiatives that adversely affect people's lives in real ways", for awhile: https://www.scientificamerican.com/blog/roots-of-unity/revie...

A lot of the ways people behave currently I think make an implicit "security by obscurity" assumption. But if intelligence really does become too cheap to meter, it will become possible to do a perfect reconstruction and synthesis of everything. LLMs are watching (or humans using them might be). Best to be good.
Can we take a second and talk about how dystopian this is? Such an outcome is not inevitable, it relies on us making it. The future is not deterministic, the future is determined by us. Moreso, Karpathy has significantly more influence on that future than your average HN user.

To properly execute this idea rather than to just toss it off without putting in the work to make it valuable is exactly what irritates me about a lot of AI work. You can be 900 times as productive at producing mental popcorn, but if there was value to be had here we're not getting it, just a whiff of it. Sure, fun project. But I don't feel particularly judged here. The funniest bit is the judgment on things that clearly could not yet have come to pass (for instance because there is an exact date mentioned that we have not yet reached). QA could be better.

I think you're missing the actual problem.

I'm not worried about this project but instead harvesting, analyzing all that data and deanonymizing people.

That's exactly what Karparthy is saying. He's not being shy about it. He said "behave because the future panopticon can look into the past". Which makes the panopticon effectively exist now.

  Be good, future LLMs are watching
  ...
  or humans using them might be
That's the problem. Not the accuracy of this toy project, but the idea of monitoring everyone and their entire history.

The idea that we have to behave as if we're being actively watched by the government is literally the setting of 1984 lol. The idea that we have to behave that way now because a future government will use the Panopticon to look into the past is absolutely unhinged. You don't even know what the rules of that world will be!

Did we forget how unhinged the NSA's "harvest now, decrypt later" strategy is? Did we forget those giant data centers that were all the news talked about for a few weeks?

That's not the future I want to create, is it the one you want?

To act as if that future is unavoidable is a failure of *us*

Yes, you are right, this is a real problem. But it really is just a variation on 'the internet never forgets', for instance in relation to teen behavior online.

Stylometry killed that a long time ago. There was a website, stylometry.net that coupled HN accounts based on text comparison and ranked the 10 best candidates. It was incredibly accurate and allowed id'ing a bunch of people that had gotten banned but that came back again. Based on that I would expect that anybody that has written more than a few KB of text to be id'able in the future.

by jacquesm

12/11/2025 at 8:15:22 AM

You need a person's text with their actual identity to pull that off. Normally that's pretty hard, especially since you'll get different formats. Like I don't write the same way on Twitter as HN. But yeah, this stuff has been advancing and I don't think it is okay.

by godelski

12/11/2025 at 8:31:24 AM

The AOL scandal pretty much proved that anonymity is a mirage. You may think you are anonymous but it just takes combining a few unrelated databases to de-anonymize you. HN users think they are anonymous but they're not, they drop factoids all over the place about who they are. 33 bits... it is one of my recurring favorite themes and anybody in the business of managing other people's data should be well aware of the risks.

by jacquesm

12/12/2025 at 12:15:13 AM

I think you're being too conspiracy theorist here by making everything black and white.

Besides, the main problem of how difficult it is to deanonymize, not if possible.

Privacy and security both have to perfect defense. For example, there's no passwords that are unhackable. There are only passwords that cannot be hacked with our current technology, budgets, and lifetime. But you could brute force my HN password, it would just take billions of years.

The same distinction it's important here. My threat model on HN doesn't care if you need to spend millions of dollars nor thousands of hours to deanonymize me. My handle is here to discourage that and to allow me to speak more freely about certain topics. I'm not trying to hide from nation states, I'm trying to hide from my peers in AI and tech. So I can freely discuss my opinions, which includes criticizing my own community (something I think everyone should do! Be critical of the communities we associate with). And moreso I want people to consider my points on their merit alone, not on my identity nor status.

If I was trying to hide from nation states I'd do things very very differently, such as not posting on HN.

I'm not afraid of my handle being deanonymized, but I still think we should recognize the dangers of the future we are creating.

By oversimplifying you've created the position that this is a lost cause, as if we already lost and that because we lost we can't change. There are multiple fallacies here. The future has yet to be written.

If you really believe it is deterministic then what is the point to anything? To have desires it opinions? Are were just waiting to see which algorithm wins out? Or are we the algorithms playing themselves out? If it's deterministic wouldn't you be happy if the freedom algorithm won and this moment is an inflection in your programming? I guess that's impossible to say in an objective manner but I'd hope that's how it plays out

by godelski

12/12/2025 at 4:02:52 PM

I have enough industry insights to prove that your data is floating out there, unprotected, in plain text and that those that are not bound by the law are making very good use of it. Every breach leaks more bits about you.

This is the main driver behind the targeted scams that ordinary people now have to deal with. It is why people get voice calls from loved ones in distress, why they get 'tech support' calls that aim to take over their devices and why lots of people have lost lots of money.

If you think I am too conspiracy theorist by making everything black and white that is maybe simply because we live different lives and have different experience.

You'll be interested in Clarke's "The Light of Other Days". Basically a wormhole where people can look back at any point in time, ending all notion of privacy.

God is different though. People like God because they believe God is fair and infallible. That is not true for machines nor men. Similarly I do not think people will like this idea. I'm sure there will be some but look at people today and their religious fever. Or look in the past. They'll want it, but it is fleeting. Cults don't last forever, even when they're governments. Sounds like a great way to start wars. Every one will be easily justified

The bit about college courses for future prediction was just silly, I'm afraid: reminds me of how Conan Doyle has Sherlock not knowing Earth revolves around the Sun. Almost all serious study concerns itself with predicting, modelling and influence over the future behaviour of some system; the problem is only that people don't fucking listen to the predictions of experts. They aren't going to value refined, academic general-purpose futurology any more than they have in the past; it's not even a new area of study.

it's great that this was produced in 1h with 60$. This is amazing to create small utilities, explore your curiosity, etc.

But the site is also quite confusing and messy. OK for a vibe coded experiment, sure, but wouldn't be for a final product. But I fear we're gonna see more and more of this. Big companies downsizing their tech departments and embracing vibe coded. Comparing to inflation, shrinkflation and skimpflation/ enshittification , will we soon adopt some word for this? AIflation? LLMflation?

And how will this comment score in a couple of years? :)

This is a perfect example of the power and problems with LLMs.

I took the narcissistic approach of searching for myself. Here's a grade of one of my comments[1]:

>slg: B- (accurate characterization of PH’s “networking & facade” feel, but implicitly underestimates how long that model can persist)

And here's the actual comment I made[2]:

>And maybe it is the cynical contrarian in me, but I think the "real world" aspect of Product Hunt it what turned me off of the site before these issues even came to the forefront. It always seemed like an echo chamber were everyone was putting up a facade. Users seemed more concerned with the people behind products and networking with them than actually offering opinions of what was posted.

>I find the more internet-like communities more natural. Sure, the top comment on a Show HN is often a critique. However I find that more interesting than the usual "Wow, another great product from John Developer. Signing up now." or the "Wow, great product. Here is why you should use the competing product that I work on." that you usually see on Product Hunt.

I did not say nor imply anything about "how long that model can persist", I just said I personally don't like using the site. It's a total hallucination to claim I was implying doom for "that model" and you would only know that if you actually took the time to dig into the details of what was actually said, but the summary seems plausible enough that most people never would.

The LLM processed and analyzed a huge amount of data in a way that no human could, but the single in-depth look I took at that analysis was somewhere between misleading and flat out wrong. As I said, a perfect example of what LLMs do.

And yes, I do recognize the funny coincidence that I'm now doing the exact thing I described as the typical HN comment a decade ago. I guess there is a reason old me said "I find that more interesting".

I'm not so sure; that may not have been what you meant, but that doesn't mean it's not what others read into it. The broader context is HN is a startup forum and one of the most common discussion patterns is 'I don't like it' that is often a stand-in for 'I don't think it's viable as-is'. Startups are default dead, after all.

With that context, if someone were to read your comment and be asked 'does this person think the product's model is viable in the long run' I think a lot of people would respond 'no'.

by npunt

12/12/2025 at 5:30:01 PM

And this is a perfect example of how some people respond to LLMs, bending over backwards to justify the output like we are some kids around a Ouija board.

The LLM isn't misinterpreting the text, it's just representing people who misinterpreted the text isn't the defense you seem to think it is.

by slg

12/13/2025 at 2:11:36 AM

And your response here is a perfect example of confidently jumping to conclusions on what someone's intent is... which is exactly what you're saying the LLM did to you.

I scoped my comment specifically around what a reasonable human answer would be if one were asked the particular question it was asked with the available information it had. That's all.

Btw I agree with your comment that it hallucinated/assumed your intent! Sorry I did not specify that. This was a bit of a 'play stupid games win stupid prizes' prompt by the OP. If one asks an imprecise question one should not expect a precise answer. The negative externality here is reader's takeaways are based on false precision. So is it the fault of the question asker, the readers, the tool, or some mix? The tool is the easiest to change, so probably deserves the most blame.

I think we'd both agree LLMs are notoriously overly-helpful and provide low confidence responses to things they should just not comment on. That to me is the underlying issue - at the very least they should respond like humans do not only in content but in confidence. It should have said it wasn't confident about its response to your post, and OP should have thus thrown its response out.

Rarely do we have perfect info, in regular communications we're always making assumptions which affect our confidence in our answers. The question is what's the confidence threshold we should use? This is the question to ask before the question of 'is it actually right?', which is also an important question to ask, but one I think they're a lot better at than the former.

Fwiw you can tell most LLMs to update its memory to always give you a confidence score 0.0-1.0. This helps tremendously, it's pretty darn accurate, it's something you can program thresholds around, and I think it should be built in to every LLM response.

The way I see it, LLMs have lots and lots of negative externalities that we shouldn't bring into this world (I'm particularly sensitive to the effects on creative industries), and I detest how they're being used so haphazardly, but they do have some uses we also shouldn't discount and figure out how to improve on. The question is where are we today in that process?

The framework I use to think about how LLMs are evolving is that of transitioning mediums. Like movies started as a copy/paste of stage plays before they settled into the medium and understand how to work along the grain of its strengths & weaknesses to create new conventions. Speech & text are now transitioning into LLMs. What is the grain we need to go along?

My best answer is the convention LLMs need to settle into is explicit confidence, and each question asked of them should first be a question of what the acceptable confidence threshold is for such a question. I think every question and domain will have different answers for that, and we should debate and discuss that alongside any particular answer.

One of the few use cases for LLMs that I have high hopes for and feel is still under appreciated is grading qualitative things. LLMs are the first tech (afaik) that can do top-down analysis of phenomena in a manner similar to humans, which means a lot of important human use cases that are judgement-oriented can become more standardized, faster, and more readily available.

For instance, one of the unfortunate aspects of social media that has become so unsustainable and destructive to modern society is how it exposes us to so many more people and hot takes than we have ability to adequately judge. We're overwhelmed. This has led to conversation being dominated by really shitty takes and really shitty people, who rarely if ever suffer reputational consequence.

If we build our mediums of discourse with more reputational awareness using approaches like this, we can better explore the frontier of sustainable positive-sum conversation at scale.

Implementation-wise, the key question is how do we grade the grader and ensure it is predictable and accurate?

I've had the same though as Karpathy over the past couple of months/years. I don't think it's good, exciting, or something to celebrate, but I also have no idea how to prevent it.

I would read his "Best to be good." as a warning or reminder that everything you do or say online will be collected and analyzed by an "intelligence". You can't count on hiding amongst the mass of online noise. Imagine if someone were to collect everything you've written or uploaded to the internet and compiled it into a long document. What sort of story would that tell about who you are? What would a clever person (or LLM) be able to do with that document?

2. When people you know say they're taking a new job to work at Torment Nexus, act like that's super weird, like they said they're going to work for the Sinaloa cartel. Treat rich people working on the Torment Nexus like it's cringe to quote them.

3. Get hostile to bots. Poison the data. Use AdNauseum and Anubis.

4. Give your non-tech friends the vague sense that this stuff is bad. Some might want to listen more, but most just take their sense of what's cool and good from people they trust in the area.

12/10/2025 at 10:11:26 PM

I think we need to stop focusing only on the AI aspect of this. Yes, it's an important component to the sort of mass surveillance system you're describing, but it's not the only component. The internet, advertising, privacy, all of these are integral to this outcome.

While I don't have a general solution, I do believe that the solution will need to be multi-faceted and address multiple aspects of the technologies enabling this. My first step would be for society to re-evaluate and shift its views towards information, both locally and internationally.

For example, if you proposed to get rid of all physical borders between countries, everyone would likely be aghast. Obviously there are too many disagreements and conflicting value sets between countries for this to happen. Yet in the west we think nothing have having no digital information borders, despite the fact that the lack of them in part enables this data collection and other issues such as election interference. Yes, erecting firewalls is extremely unpalatable to people in the west, but is almost certainly part of the solution on the national level. Countries like China long ago realized this, though they also use firewalls as a means of control, not just protection (it doesn't have to be this way).

But within countries we also need to shift away from a default position of "I have the right to say whatever I want so therefore I should" and into one of "I'm not putting anything online unless I'm willing to have my employer, parents, literally everyone, read it." Also, we need to systematically attack and dismantle the advertising industry. That industry is one of the single biggest driving factors behind the extreme systematic collection and correlation of data on people. Advertising needs to switch to a "you come to me" approach not a "I'm coming to you" approach.

To be clear...prior to this recent explosive interest in LLMs, this was already true. Snowden was over 10 years ago.

We can't start clutching our pearls now as if programmatic mass surveillance hasn't been running on all cylinders for over 20 years.

Don't get me wrong, we should absolutely care about this, everyone should. I'm just saying any vague gestures at imminent privacy-doom thanks to LLMs is liable to be doing some big favors of inadvertently sanitizing the history of prior (and still) egregious privacy offenders.

Random Bets for 2035:

* Nvidia GPUs will see heavy competition and most chat-like use-cases switching to cheaper models and inference-specific-silicon but will be still used on the high end for critical applications and frontier science

* Most Software and UIs will be primarily AI-generated. There will be no 'App Stores' as we know them.

* ICE Cars will become niche and will be largely been replaced with EVs, Solar will be widely deployed and will be the dominate source of power

* Climate Change will be widely recognized due to escalating consequences and there will be lots of efforts in mitigations (e.g, Climate Engineering, Climate-resistant crops, etc).

Interesting experiment. Using modern LLMs to retroactively grade decade-old HN discussions is a clever way to measure how well our collective predictions age. It’s impressive how little time and compute it now takes to analyze something that would’ve required days of manual reading. My only caution is that hindsight grading can overvalue outcomes instead of reasoning — good reasoning can still lead to wrong predictions. But as a tool for calibrating forecasting and identifying real signal in discussions, this is a very cool direction.
