I have absolutely no vested interest in defending Uber, but every time one of these threads pops up I feel compelled to throw cold water on it because this website is so damn obsessed with predicting Uber's doom. I have comments that are 6 years old saying "no, uber is not dying", with a thread full of angry pitchforks sure I am wrong.
Nobody cares if Uber as a whole is more "efficient" as measured by some global measure of dollars invested into the service. They care whether -their- individual lived experience is preferable. The obvious takeaway is that urban residents are happy to pay more money overall on car services, so long as those services provide a higher quality experience. People do not like feeling like the end of a cab ride might result in a game of "pretend the card reader doesn't work", people don't like to feel like their destination is an imposition on the driver who will now sit up front fuming about where you've taken him. People don't like having their sense of decency pitted against each other to win a cab in a reasonable amount of time without rudely upstreaming someone. People don't like waiting outside in the cold. People don't like being surprised by how high the meter is when they get out. People don't like having no recourse when they accidentally leave their phone behind besides calling a rude dispatcher. People like cars with nicely maintained interiors that don't smell weird.
How hard is this to understand? The average ride experience you get in an Uber is better. Uber pioneered that improved customer experience by figuring out a solution (some social, some technical) to the biggest friction points. Uber and Lyft are the 700lb gorillas in the rideshare company space, which absolutely DOES have network effects, despite the facile claim otherwise in the article. This is the basis for thinking these companies have a promising future. It's that simple. The size of the circlejerk predicting that it's all going to fall over tomorrow is so embarrassingly, transparently motivated by _hoping_ that it's going to fall over tomorrow.
