Frank Chadwick was speaking at a convention in 2011, about Striker (sci-fi minis game linked to Traveller) and the technological changes he did or didn't see coming between 1981 and 2011. I think that can speak to some tech changes we and GDW didn't predict from 1984 to now, either.
For myself, aged 16 in 1984, I think I vaguely thought that the USSR might collapse, but with no thought as to timeline. I was reading Russian, Polish, and Soviet history as much as I could, as well as military history, and wargaming what I could find.
