Uber could actually be a viable business if they gave up on being a unicorn. Right now, you can step out of an airport in a new country, pull out your phone, type in an address, and someone will drive you there. They're a universal ride-hailing service, and they could probably even charge a premium for that versus local taxis. Unfortunately, they're probably in too deep to become a medium-sized business. Also, building their own fleet of robo-taxis is insane when their current business model relies on (underpaying for using) people's personal cars.
