One missing analysis, that IMHO is the most important right now, is : what is the quality of the generated code ?

Having LLM generates a first complete iteration of a C compiler in rust is super useful if the code is of good enough quality that it can be maintained and improved by humans (or other AIs). It is (almost) completely useless otherwise.

And that is the case for most of today's code generated by AIs. Most of it will still have to be maintained by humans, or at least a human will ultimately be responsible for it.

What i would like to see is whether that C compiler is a horrible mess of tangled spaghetti code with horrible naming. Or something with a clear structure, good naming, and sensible comments.
