The future ain't what it used to be
Things Magazine has a great post on NASA-commissioned space colony art from the 70s. They comment:
I suppose at some point in the last 30 years these might have seemed remotely feasible, but today the emotions they stir are not of tomorrow's new frontiers, but of past engineering glories, nostalgia for unfettered enthusiasm and self-belief.Jon Langford's Sputnik 57 explores a similar theme. If you haven't listened to it yet, you should.
On a related topic, the Republicans are apparently terribly disappointed that science fiction is no longer what they thought it was.
