I don’t think of Uber as a force that dis-intermediates—as we olds used to say—transportation, but one that creates value for itself, its drivers, and its users, by developing a new layer that integrates them all with maximum utility. A very talented developer once told me that the secret to a world-beating service like Dropbox was to make something very, very complicated seem devastatingly simple. To me, uberizing meant trapping a series of innovative processes—phone-enabled geo-location, payments and driver management and distribution—into an app-accessible service.
That’s good framing. It’s not (just) removing a middleman, it’s better overall UX. One might even say “design.”
