This event sums up exactly why Elon is such a polarizing character. Because on one hand, this is the visionary who dares to think it's possibly feasible to shoot off rockets and land them back on barge ships in the ocean. He's going to do it all again and completely revolutionize road transport. What we've learned over the last decade or so is that it may be more difficult to put a safe self-driving car on the road than to land rocket ships back here on Earth after shooting them off into space. It just speaks to the sort of level of technical challenge and capability that is going to be required for these autonomous vehicles to be acceptable to society. And it reminds me of something somewhat related - watching him on stage there, after having just seen him on stage with Trump in Butler, Pennsylvania, I will say this: he was much more in his element here.
