That's what I thought about movies from the 50s when I was young in the early 80s. 30 years really is a long time for someone young.
There is a channel on YouTube where the "Fine Brothers" (who are a part of my generation) show kids, teens, adults, or popular YouTubers different objects and viral videos and comment.
Two of the more recent fun ones are "Kids React to Technology" and are shown...
... a rotary telephone
... and a walkman.
Generation gaps are much wider from a mental standpoint than they are physically.
