I think the human mind is better than technology, for the reason of unlimited imagination and perspective of course. If you put the idea on engineer.ai, the vision will be limited and stack to the average or lets say excellent stage. But the mind of a human is beyond on that level, just for example the weirdest dream you encounter is the real evidence on how deep the human design did.
Just adding some info, please don't be offended. If you provide a good answer/response, I recommend this to all of my friends.
My understanding is that the AI of Builder simply just automates everything using a graphical user interface to simplify things for the client or idea maker.
