Ha. 70s is a diff vibe. To me it's diffuse, unfocused, open and permeable, but no direction -- no decisiveness. The 80s is all like "We know what we want and we are going there now! You with us? Okay, come along! You're not? CYA later, alligator." Hahaha! :)
But I'm curious -- for you, where was the 70s good and what was good about it? :) haha! :)
At the time, of course, life was limited to dancing to disco and blasting classical on the Klipsch and gaining another few hundred feet uphill of mellow on Mt. Tam, but soon —maybe even by 2020*?— we'd be hang gliding in space colonies at the Lagrange points, eg https://nss.org/wp-content/uploads/Bernal_Interior_AC76-0628...
* after all, extrapolating from:
1903 - beginning of manned aeronautics
1961 - beginning of manned spaceflight
just imagine what another 60 years of aerospace would bring!
