I hope Musk has been keeping his nose clean - despite the fact that he relies too much on government subsidies, I admire his willingness to swing for the fences. While the rest of Silicon Valley sits around these days designing social media sites to intrude on your privacy and get you to provide them with free content, Musk comes up with OTA software updates for cars, pushes hard for self-driving technology, and builds powerful booster rockets. We need more tech leaders with his ambition - he might be a nut with a monstrous ego, but that describes more than a few of the men who have driven innovation in the last 100 years.
