People get upset by the 'superhero' status of Elon Musk. Nerds everywhere worship the guy, buy his cars, watch his SpaceX launches. But honestly, let him have it, I say. He's earning it. He's taking huge risks and succeeding where others weren't willing to try.
He's surfing a thin line these days. I'm not fond of the let's bore tunnels before going to mars games. But yeah, overall he bootstrapped many heavy innovations and drive all around, and inspired a lot of people. All that almost in a vacuum, and globally he's a trustworthy producer (he values value, his cars are tank secured for instance, not crass profit)
I'm of the view that boring a tunnel is part of his bootstrap plan for bringing the same tech to Mars. It's likely that we will have to dig living spaces underground on Mars and bootstrapping better digging tech by finding a good use for it here on earth first is a great bootstrapping strategy.
