Cursor fails miserably for me even just trying to replace function calls with method calls consistently, like I said in the post. This I would hope is fixable. By dealing autonomously I mean "you don't need a programmer - a PM talks to an LLM and that's how the code base is maintained, and this happens a lot (rather than on one or two famous cases where it's pretty well known how they are special and different from most work)"

By "large" I mean 300K lines (strong prediction), or 10 times the context window (weaker prediction)

I don't shy away from looking stupid in the future, you've got to give me this much
