Same claims of being overvalued/never drawing a profit we’re made about FB, Amazon, etc. too. And even if you actually believe current startups are overvalued, at least provide some kind of analysis.
The problem is twofold, for uber. First? they're losing money. If they raise prices to solve that problem, it's possible that a lot of people like me will... just buy cars again. I mean, I certainly prefer to be driven over driving, but I'm pretty price sensitive on the subject. Much more price sensitive than I am for most of the things I get from amazon.
Uber's second problem is that the difficult to compete with advantage they have, that is, that they are global, only matters to me when I travel. When I'm somewhere I've been a while, it totally makes sense to install the local taxi apps and take what is best, and most of my car hire use is in places where I am often enough to know the market. This week? Lyft is having a 25% off sale, which makes them cheaper than uber even counting the uber loyalty program and prepay discounts. Once the Lyft sale is up, I'll probably go back to Uber.
I suppose both the problems uber has come down to the same thing; the only difficult thing about replicating their business is that they are willing to lose money doing it. They just don't have a whole lot of a moat.
