They're hemorrhaging cash right now, but it's cause they are going all out into building infrastructure and tech, without bringing in significant revenue on top of that--but this is the result of one-time spends, so it probably looks far more alarming than it is.
It's certainly a huge risk, but they are playing the long game with operating fleets of self-driving cars in major metro areas around the globe. Uber hasn't ever been a fan of their human drivers and they'd like nothing more than to strike-off that line in their operating expenses.
^I think 10 years is the more conservative estimate of when that will be viable. I think between 5-8 years is most likely for cities to have significant adoption of automated transportation.
Uber is supposedly going public within the next year, so I guess it remains to be seen if the market analysts feel that the various sectors with tech development and municipal budgets are aligned properly within an acceptable timeframe for an Uber IPO to erase a significant chunk of these current losses.
