In most cases I've seen it's because they get overwhelmed by sloppy contributions from developers who do not bother to review their AI's output. Code reviews are a lot of work.

It is no more insane than doing the opposite. This whole business has yet to play itself out.

And yet it puts a stop to the tsunami of slop and it's pretty much impossible to prove anything of value was lost.

Not insane at all. Just a very useful shortcut. Not everyone wants to move fast and break shit.

It's just a form of sanctimonious virtue-signaling that's trendy right now.
