Is Uber More Like Amazon.com or an Airline?

In one of the most interesting rivalries to watch in tech right now, Uber, Lyft and even much smaller on-demand ride competitors continue to duke it out for market share by slashing prices.

My wallet thanks them. But my brain has increasingly started to wonder: Where does it stop? And how good a business can these companies be over the long-term if they keep slashing prices and, hence, margins?

Personally, these services are starting to feel more like commodities. I switch between Uber, Lyft and the taxi app Flywheel depending on who is fastest and cheapest and am pretty satisfied with the experience every time. So does this industry over time look like e-commerce, where Amazon is the clear winner at scale, or another lower margin industry that’s a lot more competitive: airlines?
