Having said that, I wouldn’t bet against Larry Page or Mark Zuckerberg. Larry has already proved me wrong with self-driving cars. I remember being at the bar on Necker about eight years ago, when he told me “Self-driving cars are my new obsession. Within the next decade, they will be everywhere.” At the time, I didn’t think it was one of his more plausible ideas. But the technology has since improved, just as Larry had predicted.
