I'm pretty sure if I knew I could never lose a dime of my billions of fortune I'd be working on teleporters, warp drives, and time machines. People would call me a genius because I could pay for the press. Musk isn't a visionary, he's just a rich nerd throwing money at really cool things other visionaries imagined before he was born (all of his companies were ideas other people already had been working on; 100%), and then failing upwards when it doesn't work out.
