Musk and Trump are severely damaged, immoral, and risk-loving. While Trump is intellectually lazy and averse to learning from those with expertise, Musk has serially recognized and exploited technological and scientific innovators. Both survived and (in some way) thrived by understanding tricks that allowed them to avoid responsibility for major mistakes and by building mystique around their personality. Musk has no monopoly over the technologies that are key to his business plans and investments in all of his business suffer from extreme key person risk. At some point, that tower of cards will fall.
