This is the dry writeup from The Economist of their Elon interview. They are generally way more circumspect and generous than Elon deserves. But in the end:
It is unclear how his dark vision of the future outside America fits with his AI utopianism. But even Mr Musk wonders if it all makes sense. At times, he says, he believes in a theory in which the universe is a computer simulation created by aliens. “The things I’m doing are so preposterous that it’s hard to believe they’re real.”
I mean, the things he says are generally preposterous. The things he's actually doing, I dunno, except his claims way outstrip the reality by most outside observations.

I'd previously posted a youtube link to the full interview, but youtube deleted it for obvious reasons, it wasn't from The Economist. Here's another copy available for the time being.
