That remains to be seen, but my guess would be that if you do it like Ladybird (with human-in-the-loop and a decent level of review) then probably yes, if you do it like Bun (1M LoC in a week) then probably no.
I’m developing three codebases right now where all of the code is written by AI (Swift, Python, Rust) and the Rust codebase requires the least pruning and has the fewest wtf moments.
