To your point, AT&T's "You Will" commercials started airing in 1993 and present both an optimistic and fairly accurate view of what the future would look like.
Wow, that genuinely gave me goosebumps. It is incredible to live in a time where so much of that hopeful optimism came to pass.
I didn't know about these ads, thanks for sharing! Can't imagine how people reacted to that when they aired — the things they described sound so "normal" today, I wonder if it was seen as far fetched, crazy or actually expected.
