People we call "inventor" on the Internet are more like showrunners on TV.
Script writers, production people, arm-twisters. It's hard work, and doing it well requires an artistic flair, technical knowledge and a good grasp of people and politics.
The myth of the inventor with his or her Aha! moment, well that's probably not what's going on. It's synthesis. Ideas being stolen and tweaked. Moments waited for. Bets made.
