"...operational infrastructure and excellence it takes to scale a marketplace like Uber's to 4 billion rides..." Nope! In the grand scheme of things, building an app, and some backend software while maintaining bunch of servers doesn't compare to building: [1] - 46 BART stations: 17 surface, 14 elevated and 15 subway stations. - 669 revenue vehicles - 112 miles of railway track - a police force with 206 legally sworn-in law enforcement officers and 90 other staff members - a wireless network that supplies cell phone service to riders underground BART isn't even that good - I live in Sydney and we are always complaining about our double-decker dead-silent very clean commuter and city rail. Buzzfeed [2] even thinks our train system is from the future! I love software - I want to make a career out of it, but we can't forget "real" engineering fields and the effort that goes into them.
