I'm going to go against the crowd and say that Uber survives as a business for now. They may scale back expansion and they might raise prices. They may even get acquired at a lower valuation. But I bet they'll still be operating.

I think their burn rate is almost surely the result of subsidizing expanding markets. I can't imagine established markets being anything but ludicrously profitable.

Disclaimer: I don't necessarily like Uber, I've never even used them and I know almost nothing about their (former) CEO outside of headlines.
