> Interestingly, the pro-AI folks almost universally doubled down and said that I should use AI more to gain more confidence – ask how can I test it, how can we verify it, etc – to move my confidence instead of changing how review works.

I think this is a good suggestion, and it's what I usually do. If - at work - Claude generated something I'm not fully understanding already, and if what has generated works as expected when experimentally tested, I ask it "why did you put this? what is this construct for? how you will this handle this edge case?" and specifically tell it to not modify anything, just answer the question. This way I can process its output "at human speed" and actually make it mine.
