We see a lot of "core member of great thing founds own thing" and you really want to see them succeed but having an organization succeed takes a a lot of people with lots of different skills. I'm not convinced that any given jumble of highly talented folks actually produce something if we somehow ran a but of iterations of "jumble of highly talented folks".
I've heard plenty of stories of such folks going their own way to be stopped by basic business type problems like project management, just managing people, maintaining focus, raising money and keeping investors happy, etc.
