The other thing Uber has to do is optimize well. It needs to state competitive with Lyft for both passengers and drivers, minimize driver churn (but not too much), optimize matching, and charge predicted fares accurately.
Uber also processes an insane number of transactions. Not quite Visa, but I'd guess it's in the top 5% of volume as a merchant.
Uber also was wasting a huge amount of time and energy and most of the engineers didn’t have anything productive to do. At least that’s what I gathered from some ex Uber folks.
