Any people 'in the know' care to elaborate on that ?
There are actually quite strong connections between computer nerds and the counterculture of the 60s/70s. If you’re curious I recommend the following books:
# What the Dormouse Said: How the Sixties Counterculture Shaped the Personal Computer Industry / John Markoff. A great book with many fascinating characters.
# From Counterculture to Cyberculture: Stewart Brand, the Whole Earth Network, and the Rise of Digital Utopianism / Fred Turner. Also an interesting read, but much less accessible than Markoff’s book.
# The Cuckoo’s Egg: Tracking a Spy Through the Maze of Computer Espionage / Clifford Stoll. Very good book, reads like a detective novel in a Berkeley setting.
