Anybody seen iRobot with Will Smith? There is a very nice contrast between humans and robots, highlighting that robots can't write a symphony or draw Mona Lisa, also stating that neither can majority of humans. Really though provoking.

Elon knows what he is doing. Zip2, Paypal, SpaceX, Tesla, and others have all been successful projects. Tesla will just need more time, as it relies on society a bit more than the rest of the stated companies.
