IMHO, the hippie generation did not end in the 70s. The movement continued with hippie Steve Jobs who counter-culturally changed the world with the way he did tech.
"In a book interview, Jobs called his experience with LSD "one of the two or three most important things I have done in my life." As Jobs himself has suggested, LSD may have contributed to the "think different" approach that still puts Apple's designs a head above the competition."
But now that Steve is in the ICloud, I guess, the spirit of "hippieness" has died with him.
