It seems that Elon Musk used to read the ghost in the shell (攻殻機動隊) as well... which very soon will have a Hollywood version in every cinema. The problem I find on Elon words is that everything he says tends to be oversimplified and put in a dichotomy without much fundamental basis (just because something is plausible is not more closed to happen) this is in one hand great to create a vision, but I would say that at the same doesn't play well with the scientific method...
