> The Hyperloop, is something Musk spent over a calendar year and numerous engineering assets working on before he decided to give up and open-source their work. If any of his projects was an unreserved failure, it was the hyperloop. Can you provide me with a source on that? During that time he was full time for Tesla and SpaceX and they were very busy during that time with other projects. So I can't see how this much engineering was put into it. Also, not doing a project is not the same as failing at doing something. The result of the investigation was clearly, I think its a good idea but I have no time to do it. Maybe somebody else will. I think he still hopes to eventually put a Hyperloop type system into a boring tunnel, but he thinks shorter range solution are more important and tunneling technology needs to improve to make it viable. > SolarCity I agree it could have been a failure, but also don't know that for sure. > I don't get why you're so upset about this. I didn't say Musk was horrible. I just pointed out a lot of his projects tend to fail. I am not upset, I just pointed out for the most part his projects do not fail. You pointed to one project they didn't actually do more then a initial technical evaluation on. And on project that could have failed, but actually didn't. I think objectively if any person said 'I'm gone do X project' (that was considered incredibly difficult), I can't think of many that would have more credibility then Musk (ie Tesla, SpaceX or a new company). A humanoid robot is a risky project for sure and it does not seem to be the same level of importance as batteries or reusable rockets, so maybe they will abandoned it at some point.
