Key distinction. As well as assembling an incredible logistics system. Uber has... a trivial app that's already been cloned dozens of times?

Uber's saving grace, if it will ever get one, will be autonomous vehicles. First the technology has to get good enough, then the law has to catch up. All while Uber is just dumping cash to fend off the aforementioned dozens of clones by artificially deflating their prices?

My bet is that they'll run out of time/money.
