I don't think trusting that someone wrote the code was ever a good assurance of anything, and I don't see how that changes with AI. There will always be certain _individuals_ who are more reliable than others, not because they handcraft code, but because they follow through with it (make sure it works, fix bugs after release, keep an eye to make sure it worked, etc).

Yes, AI will enable exponentially more people to write code, but that's not a new phenomenon - bootcamps enabled an order of magnitude more people to become developers. So did higher level languages, IDEs, frameworks, etc. The march of technology has always been about doing more while having to understand less - higher and higher levels of abstraction. Isn't that a good thing?
