I think the problem is more that people doubt Musk's sincerity. And I wonder, to be honest, how it’s possible not to. Musk is no Wright and no Bell. He should be placed in the same category as people like Bernie Madoff, Charles Ponzi, and Gregor MacGregor. But your perspective contains another flaw: In hindsight, we see the big, daring projects that were successful. What we don’t see are the countless projects that failed. That skews the cost-benefit analysis a bit. Especially since large projects have far-reaching, often negative side effects. You can admire Hannibal for his crossing of the Alps, but no sane person would want to be one of the many soldiers who froze to death in the process.
