Being a parent gives a whole new perspective on AI and robots. The guy uses the term “motor babbling”. The machine eventually learns to walk on its own much the same way babies learn to speak and walk. It’s kinda cool being part of the generation witnessing the closing gap between humans and machines. I think this concept is unpalatable to people (and even a few friends) because of the human ego. We used to fancy ourselves being the center of the universe and put up a lot of resistance to the idea that we orbit the sun, which is one of many stars out there. The next big shock will be the realization that machines can be truly sentient and not philosophical zombies.
