"prediction re the end of spreadsheets

AI code gen means that anything that is currently modeled as a spreadsheet is better modeled in code. You get all the advantages of software - libraries, open source, AI, all the complexity and expressiveness."

“Anything that is currently modeled” would be true if we could guarantee the correctness of AI-generated code.

Business people prefer the familiarity of spreadsheets, or at least some kind of grid. At the same time, I am working on this software out of frustration with spreadsheets, because users are forced to translate A1*B2-style addresses into business meaning.

So I agree that code is one possible direction. But I think there is also a middle ground: business rules over dimensions. Enterprise tools like TM1 have explored this direction for decades.

the only way that's possible is if you can use a spreadsheet to test the code.

I made OM Core public today.

It is an early alpha multidimensional modeling engine. The main idea is to separate the model from the grid: dimensions, cubes, rules, and views instead of spreadsheet cell formulas.

I am looking for feedback from people who have built or maintained spreadsheet models, especially on whether the abstraction is understandable.
