Uber is not a real business. Nothing about hiring a driver or maintaining or running a car is cheaper now than before Uber. Uber will never be profitable unless people are willing to pay the same amount as for regular taxis or for a private driver (i.e. expensive).
Airbnb on the other hand is a real and vastly profitable business. Yes there need to be tighter regulations because we don’t want Airbnb everywhere. That will have a non-trivial effect on its business. But even after regulation it remains a very profitable and highly appealing consumer and business product.
The other difference is that Uber just gets you from A to B. I will never remember the car nor the driver. Even if the driving experience is great, I won’t be telling my friends about it.
Airbnb on the other hand provides memorable lifetime experiences.
No comparison.
