    I do appreciate him setting an unreasonable goal and failing halfway there while the rest of the world seems content with stagnating.

This is underrated. I write this a someone who is half appalled and half amazed by Musk. How much that Tesla has already achieved in their self-driving efforts is incredible. Leave aside Musk's vision, it also means they must have an absolutely stellar engineering team working on this problem. Creating and maintaining this team is a huge feat by itself.
