Does he really have hyperloops to dream up and Mars colonies to plan, or is that just marketing drivel to appeal to certain types?
Well Mars is for sure the plan. He absolutely wants to build a city on Mars, and he absolutely has made strides in that direction with the starship. I'm not sure I'd want to live in muskberg though...
Also to his credit, the world has electric cars now. It was Tesla that made that happen, it was not inevitable. The traditional auto makers were resisting electric vehicles really hard, they did not want to build them... They only started building them to not be left behind.
I agree that he seems to have turned into a white hot ball of crazy. But his companies have had a pretty big and quite positive impact. I mean, compare Tesla and Coca-Cola, which is really doing more for the world? Compare SpaceX and Raytheon, both of those companies make rockets, but Raytheon makes them exclusively with warheads... I just look at what musk has built and I don't see the problem that everyone else here seems to.
