I see a lot of writing like this about LLM's ability to generate code, but I'm a lot more interested/optimistic about their ability to provide value by reading code. Being able to point to a github repo and say something like "explain this codebase, highlighting key functions and potential refactoring routes" would be really helpful. I've trialled that a little bit with codebases I know well and the results aren't yet helpful beyond a very high level. I think it's a pretty reasonable goal to aim for though, and this kind of codebase parsing would be much more of a net gain than just generating a tonne of functional but suboptimal code.
