I think you're describing things we already knew long before this era of AI. Less code is better code, and the vast majority of bugs come from the devs who "hate the boring easy bits".

I disagree that this has anything to do with people needing a break. All code eventually has to be reviewed. Regardless of who or what wrote it, writing too much of it is the problem. It's also worth considering how much more code could be eliminated if the business more critically planned what they think they want.

These tensions have existed even before computers and in all professions.
