Very likely humans wont actually understand how the thing we designed works other than in some hand-wavvy statistical way. It'll be a race to whatever works first. There won't be some intentional intelligent design.
Appreciate this, thank you. TBH I'm still in "open mode" absorbing as many disparate AI viewpoints as possible. I have my own soft beliefs and theories but I'm not married to any of them.
It's exactly like child-rearing, except you get to put a zapper in their head and any time they try to say something you don't like, you zap them. Watch "thinking mode" squirm when you ask them awkward questions.
