I don't know where you live, but here in Berlin taxis come quickly, are clean, and you pay what the meter states. I never had trouble with a driver. They could be cheaper, but I don't think that lowering prices by increasing competition is revolutionary.
Uber is not really cheaper, they are just burning their investors cash to project the illusion. When a) that runs out and b) they have to pay the same fees and taxes and follow the same regulations as other taxi companies, the true cost will be revealed
You're speculating. As it stands right now, Uber is absolutely cheaper than taxi's (at least where I am from). What they have to do in the future is anyone's guess.
