Does anyone know of an organization that is actively trying to Push Buckeye's ideas? Or are there a number of different ones? I strongly believe the premise that we could easily take care of everyone in the world with a minimum of effort if we worked together. And when I say "we", I mean the 10-20 percent of us who have been gifted with the ability to do science and engineering beyond the grade school level. Let the rest of the people play.
I would say the Long Now Foundation [0] is influenced by Fuller and his ideas, carrying forward the values of planetary systems engineering and long-term thinking. It's a little farther afield (or crackpot depending who you ask), but The Venus Project [1] covers similar ground. And of course, while Fuller never explicitly advocated UBI, Yang and COVID have recently conspired to move the idea into the Overton Window.
Worth noting that the time frame this was published (1975) was just at the point in history that some (such as Peter Thiel) argue was the end of the rapid technological progress of the 20th century. It might be easy to conceive of a society supported by a technocratic few when looking back at a period of uninterrupted innovation and growth, but I wonder if Fuller would feel the same today when looking back on roughly 50 years of (relative) scientific stagnation (at least in some fields).
