I'd like to point out the huge difference between specialized AI and AGI (Artificial General Intelligence). Specialized AI systems have been in use for decades and improving daily as technology improves. It is behind Googles self-driving cars and that's what Elon is interested in.
On the other hand, Hawkins is afraid of AGI and warns us not to develop it. While there is some academic research being done in that area, it is very far from reaching practical levels and questionable whether or not it should be developed from a philosophical point of view.
What I am trying to emphasize is that there is a huge difference and it requires a serious concentrated effort to implement AGI, while a specialized AI is much easier and more practical to implement and there is no "danger" that your self-driving car suddenly develops a conscience and becomes self-aware. That idea belongs to the Hollywood scripts and should remain there.
