This is the closing credits theme from 'The 21st Century', a Things-To-Come show by CBS News that ran from 1967 - 1969, and was narrated by Walter Cronkite.
Little did Walter Cronkite or CBS News, or anyone else in 1967 - 69, have any idea just how trashy the future would be. Sure we got The Internet, fiber-optic technology, laser surgery, etc. But we also got Internet porn, botox, Honey Boo Boo, and Facebook memes.
The only reason we never pursued space exploration any further was because we're too lazy and cheap, not because it's any more difficult than it was in the 1960s. Besides, we don't want to miss 'American Idol.'
