Yep.
In my experience human design -> agent code -> agent review -> release -> agent observer, does not (at all!) work. One absolutely has to be understand what is going on, how the system works, how the H/W works, etc, to catch agent errors.
The proposition of us losing those skills is terrifying.
Maybe AI will get better and we truly won't need a human in the loop. Then please also have all PRs signed by whatever model wrote them, and do not come to me for trouble-shooting.
