We might be witnessing some survivor bias here based on our own human conditioning. Successful PRs aren't going to make the news like the bad ones do.
With that said, we are all dealing with AI still convincingly writing code that doesn't work despite passing tests or introducing hard to find bugs. It will be some time until we iron that out fully for more reliable output I suspect.
Unfortunately we won't be able to stop humans thinking they are software engineers when they are not now that the abstraction language is the human language so guarding from spam will be more important than ever.
