I'd hate to be Uber right now. The early innovators always bear the full cost of discovery and paving the way for future entrants who will gladly waltz right in once Uber establishes itself in cities by lobbying and fighting regulation. The barrier to entry is not as high they make it seem and like Groupon, a focus on future potential earnings without facing realities, almost always ends up in favor of late market entrants. I recall Peter Thiel talking about this in more detail how you should never be the first at anything and that if you can't build a monopoly you will face the same fate that other first movers have met.
