SolarCity failed (and he had to buy it back himself with Tesla), Paypal was a success but it wasn't his, his part was x.com which was kind of a failure on its goal and had to sell (just because it sold for a lot of money doesn't mean it succeeded, in the terms of "success" we're discussing in this thread). Tesla has yet to make any money and fails to meet its deadline, and it's yet to see how it will far now that the car giants are turning to EV (especially with many countries setting deadline in 2016 and 2017 about the end of non EV cars, which jolted all the big ones into joining). Space-X is for me his one real success so far, it leaned on a lot of public funding to do it so it's really not the kind of things usual for HN, but they said they would re-use when everyone else said "can't be done" or "not worth it", and they're getting there.
