where i live, downtown, uber is nearly equivalent to taxis. pros for taxis: you have to wait less time, you can tell ahead of time if they have air conditioning, and pricing is predictable. cons for taxis: uber is always available, you know what you're paying before you get in, and taxi drivers rob you every chance they get, while uber drivers never do
where my girlfriend lives, in the suburbs, taxis don't exist, so uber/didi/cabify is the only option other than taking the bus (which doesn't run at night) or walking (which is dangerous, especially at night)
'disruptive' innovations are worse in important ways than the incumbents they challenge, but much cheaper; from the perspective of the consumer, this isn't true of rides from uber or lodging with airbnb, but from the perspective of the provider, this is extremely true of uber and airbnb, which are 'competing' with the taxi medallion mafia and the regulatory regime established to protect established hotel chains
getting a taxi medallion or getting licensed to open a hotel are enormously more expensive than signing up with uber or airbnb
