As a society, are we ready for self driving cars? It seems to signal the start of the next industrial Revolution, with truckers and taxi drivers going extinct, with more industries to follow. Machine learning has so far been kind of in the background, with this it's very front and center and will directly impact millions of people. Also, I've always wondered, if self driving car crashes who is legally liable? Is it the programmer or the occupant?
