Is this actually true? I'm not sure what younger means but pretty much every anecdote of innovation i know is mostly late 20s early 30s engineers with a few YOE and a couple exceptions of whizzkids straight out of college (e.g Facebook). Genuinely quite interested if there is evidence round age and innovation in Tech.
