There’s nothing resembling a “sharing economy” in an Uber interaction. You pay a corporation to send a driver to you, and it pays that driver a variable weekly wage. Sharing can really only refer to one of three occurrences. It can mean giving something away as a gift, like: “Here, take some of my food.” It can describe allowing someone to temporarily use something you own, as in: “He shared his toy with his friend.” Or, it can refer to people having common access to something they collectively own or manage: “The farmers all had an ownership share in the reservoir and shared access to it.”
“History shows a typical progression of information technologies, from somebody’s hobby to somebody’s industry; from jury-rigged contraption to slick production marvel; from a freely accessible channel to one strictly controlled by a single corporation or cartel — from open to closed system.” — Tim Wu
By 1997, computer scientists were fed up with the limited options for generating random numbers, so a team at SGI created LavaRand, which was a webcam pointed at a couple of lava lamps on a desk. The image data from the camera was an excellent entropy source — a True Random Number Generator (TRNG) like Turing’s — and it could generate 165Kb/s of random data. In Silicon Valley fashion, the lava lamp rig was quickly patented.
