My experience is the AI has somehow thrown discipline and accountability out the door.
Folks break everything all the time and looking at their PRs and messages are clearly just having the AI respond to everything for them and actually have no idea what they're doing.
And then other people doing the same thing approve their work (presumably not reading or understanding any of it) because then the other person will do the same for theirs.
Hopefully my experience is an anomaly though :)
