Elon Musk is hard to love. Elon Musk is hard to like. On his way to becoming the world’s wealthiest person, Musk has emitted so many metric tons of self-indulgent puerility he might have violated the Paris Accords.

But one need not find Musk personally or politically appealing to appreciate that his contributions to humanity could end up being profound.

Through his endeavors in solar power and electric cars, Musk might do more to combat climate change than just about any lefty environmental activist or politician you can name. Musk looks even better when judged against other globe-straddling billionaires in his orbit. His is not an empire built on inheritance, dumb luck, monopoly or, subsidies notwithstanding, insider access. Indeed, his businesses seek to undermine some of the most harmful and politically entrenched industries on the planet, among them defense contractors, utilities, oil companies and combustion-engine automakers.

There is also something straightforwardly inspiring about Musk’s story. After a troubled childhood in South Africa, he immigrated first to Canada and then to the United States, put himself through college and made his own fortune through unending hard work and in pursuit of ambitions far grander than slapping “like” buttons all over the web. Even Musk’s bluster is excusable because underneath the big talk he has repeatedly delivered on his far-out promises. He makes innovative products that work well, that delight customers and that are on balance probably good for the world. Isn’t that the best one can hope for from capitalism?
