Seems people read the blog but not the code, I looked at the stated rewrite of Numpy in Rust: > As an introductory project, I rewrote Numpy in Rust. It was great fun. That's not a rewrite at all it's just a wrapping of an existing linear algebra Rust library (faer, blas, etc..) with a more Numpy like API. It seems to me that every AI project I look at is just a mashup/wrapper over existing things. Where are the real bootstrapped new things with AI ? Is there any big OSS project (Linux kernel, postgresql, Django, whatever) with serious bugfixes or new features implemented by AI that we could look at ? Are so much people in programming implementing middleware / wrapping existing API all day that it gives them a feeling of liberation to be able to delegate those tasks ?

  There's a good thread in there highlighting the fact that a novice wouldn't be nearly as successful as the OP who has the experience to guide the LLM.

  Zed on Linux is buggy as hell. On macos it's somehow more stable. Maybe Zed is indeed a "good" example of Ai-coded products.

    This is a thing you can credibly say only if you've never used a popular new non-mainline editor. Sublime Code was "buggy as hell" too; all new editors are. Editors are incredibly difficult to do well. And Zed is doing it on hard mode, cross-platform.

A lot of jobs are providing the glue between other pieces like this and not inventing new algorithms and such. Perhaps this is why there is such a divide in sincere opinions about AI.

  Which does indicate that even if AI becomes good at coding, we will still need humans to glue all the AI stuff together.

  Incredible. If I get production ready bm25 and incremental view maintenance in postgres, it really will do everything I care about. Especially with the browser/client synch maintenance stuff people are working on.

    Yes TJ is very experienced and smart. But no he would not have been able to build this in a few months by himself without AI. In fact he uses Claude so much that he goes over the max subscription and spends thousands of dollars each month on tokens to continue delivering this fast. AI is a big multiplier for experienced folks like him.

Yes The overwhelming majority of production code are simply wrappers and APIs calling existing frameworks and libraries The type of projects you’re talking about are so unbelievably rare that almost nobody starts them or makes progress on them because predominantly they are social organizations that happen to export code

Blas and faer are used only for small corners of the API (linalg and fft) which is exactly what numpy does. I encourage you to follow your own advice and look more closely at the interaction of ufuncs, strides, and dtypes.
