Depending on codebase complexity, an AI's understanding after roughly an hour could match a human's after a few weeks, but not a human's understanding after about two years working on that codebase.

“codebase very fast like in the course of maybe like you know significantly less than an hour potentially much less than an hour and then it's understanding of the codebase will like plateau a little bit where it won't get as deep of an understanding as a human would have gotten over a much longer period so it's sort of like an ai in an hour can match a human with a few weeks maybe depending on the details of exactly how complicated the codebase is but then it won't match a human with like you know who's been working on that codebase for like two years or whatever”
