The reason I left the cryonics organization I joined in the '70's - the main reason - was that the guy running the show made me seriously worried about that very outcome. He was arrogand enough, before he figured out how much it was costing him, to tell all comers that he wasn't content to be one SI among many superhumans. He planned to take over the whole show. Some readers will probably recognize of whom I speak. I took him seriously then and he behaved consistent with that attitude until he created some disasters for the organization he lead and ended up resigning in disgrace - but that was about a decade later.
