@Linkshaender @gadi Please read the article I linked (again)! A CPU bug is a bug and as you said, we sometimes spend insane resources to fix it. We can avoid looking at microcode because of the deterministic contract and if it's not solid, we're screwed. CPU vendors (and any proper engineer) do a lot outside of testing and QA to make sure the abstractions hold, incl. having a good design.
In contrast if the LLM decides to use sqrt for addition, the LLM works as intended, good luck building your castle on farts!
This can (and does) happen because ppl task the LLM with domain modeling, and it sucks at that because reasons. When I write asm/C/Java/..., I do the modeling part.
I do agree with your conclusion though: developers/engineers will stay. Because they are the ones who can do proper modeling. As many said before me: writing the code has never been the hard part.
