There are some good and some not so good among these companies. Uber is a taxi company with an app. Cars still cost the same as before to run, drivers still cost the same as before, all costs are the same as before. So once the subsidization by VCs stops, Uber rides will be as expensive as any other ride. Self-driving cars will not save Uber either. There is no network effect with self-driving cars, and once the technology is ready it will be commoditized, and Uber will have no advantage.
As a rider, it's great to use it while you can, but there is no actual business there.
Airbnb on the there hand has all the advantages people like to see in a business.
