I've uncovered some -2x engineers recently - who cause long-term problems with their changes that more than one person has to unravel. It's usually comes as a surprise, some going back to look at who approved MRs, and loud ranting and cursing as you find a murder trail of laziness or incompetence. It's breathtaking. I'd trust some people with AI as much as I'd trust myself operating a machete - a tool best left to someone else.
