That's a good point about the carpenter getting the framing wrong. If that happened, it would be caught during the required inspection (by someone else), and the construction would be halted until it was fixed.
The issue with using AI as a tool to build software is that the inspection step is not required. I'm not sure an AI-generated description is a sign of bad inspection processes. I think maybe in the case of a game mod, the description is not as important as it would be for some software that someone is selling.
I guess my point is that quality can't be assessed merely by whether something was built with AI. A trustworthy team will have carried out inspections along the way. The question is how can we know that?
