When I first watched this some time back I felt the usual responses like it was defeatism and apocalyptic, but watching it a few times I can't help that George was just telling it plain, decades ago. When you get to the part about the viruses it's chillingly prophetic. Ultimately he's right: the earth with be just fine (unless a comet wipes it out for good), but we're done for, most likely. George Carlin, Master Jester, in the ancient sense of the term.
George's material certainly stands the test of time. I would just offer this one update: as he said, back in the day, the extinction rate was about 25 species a day. Now its over 250 a day.
@David1955 Actually 250/day may be a little high. Current estimates are running around 150 -200 per day. Still, it way higher than the natural rate without human impacts .
Wisdom in comedy.
In his later years, he became more than a comedian, more like a social commentator and a prophet.
George wasn't a classically well educated man, as he often said, but he read voraciously and widely, and was well educated in life, combine that with incredible honestly, a passion for calling out bullshit, as he called it, and a man with an insight of prophecy, in a non religious sense, and you have as a result an extraordinary man. Much missed.
