As you can see, Stephen finally asked what we've all been wondering: is Elon Musk a super villain? I mean, he was very touchy in some parts of the interview, looking like he'd snap on the host at any moment... but he didn't. And come on. Nuclear weapons on Mars? Sounds just like a super villain. In reality, it would just be 'the quickest way to make Mars' atmosphere hospitable,' but still, it screams Moonraker.
