My parents weren't just released from prison after having been locked away from society since the 80s. Nor have they just awoken from 35 year comas. Sure, they'll have a different perspective than someone who doesn't remember the 80s but they'll surely also have a different perspective from someone with a more abrupt and recent introduction to the latest modernity.
They'll have watched The Jetsons, Blade Runner, 2001, 2010: The Year We Make Contact, and a host of other science fiction that all made the year 2000 look like the year 2100. In 1981, we sure didn't think the Berlin Wall would fall and the USSR would cease to exist a decade later (unless that came about by an apocalypse).
You don't exactly need time travel to get an opinion from someone who lived the 1980s... try asking your parents?
