For every genuine tech innovation, there are thousands of half-baked ideas that fizzle out, often because “disrupting” an industry is little more than slapping a new label on old technology and calling it a breakthrough. It doesn’t have to go full Juicero to be ridiculous; you wouldn’t believe how many times Silicon Valley has, perpetually in a cloud of its own farts, reinvented the bus. When innovators enter industries that don’t need to be innovated — and in some cases, can’t be — they try anyway, spinning their wheels and running their mouths until the jig inevitably ends.
