You probably missed all the "soft science fiction" movement after the sixties... ( http://en.wikipedia.org/wiki/Soft_science_fiction ).

What you describe was 30-50s style "hard science fiction" --think Asimov, Clark, etc

I'm aware of what "soft SF" is. What I was getting across is that it is much more a rebellion against SF than a continuation or evolution of it.
