I interviewed at Uber a few year ago, pre-IPO (bullet dodged!). Their pitch, from a senior VP, was all about self-driving, even though I wasn't even looking at a self-driving role. But at the time, it struck me as a complete farce that this company that made its success by replacing cab drivers, was trying to convince me that it's actual success would come from them cracking a problem they hadn't cracked, which no one had cracked, which was not even close to being proven feasible.

Somehow they felt that they would simply "be the world's transportation" (their stated goal) based on a completely unproven technology.
