They had it all
I like to remind my younger peers that technology does not show a steady progression pattern. In the past we can see long forgotten examples of ideas were not only ahead of their time, but that are still ahead of our own. PLATO was such a thing.
In the 70's they had social media, collaborative editing, wide-area multi-user games, hypertext, instant-messaging and e-mail. And they had it in graphic terminals that showed pictures we would not be able to see on a desktop computer until the mid-80s.
They had it all.
Enjoy.
