I don't like some of Uber's ethics but its execution overall has been exceptional. There is one impressive technical component around matching up riders along the same route. Otherwise, the Uber service is mostly just well-executed technology. But where Uber is way beyond others is operations, scale, marketing, etc. All worthy characteristics even if they don't resonate so much with a pure technical crowd. Also, on a gross basis, Uber's 20-25% take rate makes it wildly profitable.
