Good point. When I was younger, I'd have argued the collective action problem is just a matter of time and development, but I've now seen dozens of technologies stalled out. I firmly believe it's the reason we don't have flying cars. I can sketch out all the pieces needed to get there, which in the simplest-to-explain version consist of a few regulatory changes, an autogyro, a control system, and some infrastructure, but those few changes easily add up to an obscene amount of money. Once invested, the next competitor can do almost the same thing almost out of a garage. Lots of medical technologies too. And medical systemic changes. Education too.
