This this may be in danger of going into pedantic territory, I don't feel this is true at all. The prevailing discussion in the late 80's/early 90's on the tech boards (BBS) I frequented were all talking about networking and how computers were one day all going to be interconnected.
In fact FIDONET and the like probably had already met that bar, in an early PoC sense. Lots of folks in that space had the vision of at least a nationwide network of 24x7 connected bbs' if not the entire picture. You also had a lot of guys working in private industry, who operated small "national" or regional networks between a few sites at that point.
I still remember a day in 1994 when I played Chess over the Internet with someone in South Africa - thinking that holy crap, the world we had been dreaming and talking about for 10 years finally was coming true.
