I think this is a silly premise for a thread, and since I was born in the 50's I have the historical perspective to know. First of all "American society" has never been monolithic and limited to just a few topics. The vast majority of people have their own personal lives to live, jobs to do, entertainment to enjoy, and "space" is just one of MANY topics that they are bombarded with. The vast majority of people don't "dream" of space.Why? Because space up until now has seriously failed to live up to the hype being pushed not only by NASA, but also by the entertainment industry.And the real applications of space, such as the International Space Station (ISS), it turns out that being safe in space makes for boring news cycles, so what is American society supposed to be excited about?As for "the future of space", put that in the same category as "the future of work", or "the future home". So called "futurists" have been trying to imagine the future for a long time, and they rarely get it right.So what is the "American society" not getting excited about that they should be excited about?
Societies don't dream and there's never been a better time for space travel, manned, exploration and commercial. Don't push your beliefs and burnouts onto anybody else. Apollo wasn't the Golden Age. This is.
American society ought to be excited about privately-funded mega rockets like the Falcon Heavy, New Glenn, and Starship as well as Virgin Galactic's suborbital passenger flights...
...because many people don't know that Robert Heinlein became the first person to conjure up the notion of privately-funded spaceflight when he published the 1950 sci-fi novel The Man Who Sold the Moon, years before NACA was renamed NASA in 1958, and the recently completed first three commercial flights of SpaceShipTwo are the first steps in fulfilling Burt Rutan's dream of routine commercial suborbital passenger spaceflight.
