Don't forget the biggest scifi guy turned cult leader of all L. Ron Hubbard
L. Ron Hubbard is more like the Zizians.

I'm reminded of a silly social science article I read, quite a long time ago. It suggested that physicists only like to study condensed matter crystals because physics is a male-dominated field, and crystals are hard rocks, and, um ... men like to think about their rock-hard penises, I guess. Now, this hypothesis obviously does not survive cursory inspection - if we're gendering natural phenomena studied by physicists, are waves male? Are fluid dynamics male?
However, Mr. Yudowsky's weird hangups here around rigidity and hardness have me adjusting my priors.
