Oh I agree totally. I find it to be one of the coolest parts of the whole thing: Getting the AI to help put together the docs that will be handed to the AI. But the "quite technical people" that I referenced are not "full technical people"; I would lose them if I tried to explain the above to them.

I also really like telling the AI, "while we are hacking our way through the jungle trying to figure out how this thing should be built, at the same time, I want you to keep a design document up to date so that, if I asked you to rebuild the whole system again but without all the false starts etc we went through while we were figuring it out together, you could do so."

I probably won't use any of the "zombie clone" versions of my app that get built from the AI-generated design doc, but the fact that the zombie app (and design doc) look good at a casual glance, and the design doc is not 200 pages of AI bloatware verbiage, seems like good evidence that if a human expert needed to step in and save the system from some big surprise, that design spec would be found to be exactly what that human needed to help find the problem.
