He's only human after all. He got rich on the internet early on, then started a few more companies that are doing fairly cutting-edge things.None of that means he's on to something when he talks about our universe being a computer simulation. He's just as error-prone as anyone, the mind can trick itself into believing almost anything. I have no doubt that like other tech visionaries, he uses marijuana (maybe a little too much?), which could explain this line of thought. He's also a little too sure of himself, bolstered by the yes-men around him. The sad part is all the millions of Elon fans might hear this and start to think it's possibly true. It's a shame he said this publicly, it doesn't make him look smarter for having said it.
