alt Hacker NewsI don't think they ever will on the "maintainable" part until their absolutely atrocious memory gets improved at least tenfold. (and no, the tricks we deployed until now aren't enough)
They already are better than most humans at writing code for sure but even the best SOTA model is worse than your average intern at memorization.
That's the entire point of the "maintainable" part: someone with no "memory" of what was written where and why should be able to walk into the codebase, understand how it works, and be able to make a sensible change to it without setting things on fire.
Someone with "memory" should be able to do the same faster, but having that memory should not be a requirement.
Whether that "someone" is a freshly onboarded mid-level SWE or a mid-tier coding LLM is largely irrelevant.
