There's weirdly many people who touch on the work around transhumanism but never heard the word before. There's a video of geohot basically talking about that idea, then someone from the audience mentions the name... and geohotz is confused. I'm honestly surprised.
The transhumanists tended to be philosopher types, the name coming from this kind of idea of humanism:
>Humanism is a philosophical stance that emphasizes the individual and social potential, and agency of human beings, whom it considers the starting point for serious moral and philosophical inquiry. (wikipedia)
Whereas the other lot are often engineers / compsci / business people building stuff.
