With so many competitors in the marketplace, such as Lyft, Gett, Via, Juno, and now Google, seems like Uber's leadership position is at risk. There appears to be very little differentiation between all of them, and while Google is starting out with carpooling, it is just a matter of time before they expand. Not sure how any investor could ever justify Uber's $60B valuation. In 10 years, will likely be 1/10 of that.
