Well unfortunately. this has been going on for years.
I remember back in
1983 in a prestigious Toronto Technical college, having read a spate of
remaindered issues of "Electronics" and "Byte", I asked about UNIX,
only to
be greeted with looks of incomprehension by all my teachers. Needless to
say, I was a little less awed by their acuteness after that.
OTOH one of my professors from UC Riverside Cal. spent a year a Bell Labs,
and was incomprehensible for a good year or more afterwards. Just too
leading edge for just about ANYBODY to grasp outside of the immersed
environment of Bell Labs.
