I agree with the author who said that is ahistorical...at least from my, and the people I grew up with's, perspectives. I grew up with computers in the 70's and 80's and while you may be thinking of centralized computing (minicomputers and mainframes), the personal computing revolution was widely distributed, not centralized in academia. BBSes, swap meets, user groups, even the corner Radio Shack was where 'computing' was vibrant and active. (And the magazines...SO many 'zines!)
We may be talking past each other, but my experience of computing in the 70's and 80's was definitely not academic.
