Plenty of people are still alive that were using the internet 20 years ago.
I think you’re confusing what scifi predicted it would be like in movies/TV which is almost always over exaggerated because that’s what sells.
Even when that stuff came out, no one back then took the crazy stuff seriously, if anything serious predictions underestimated what it would be like today.
I don’t think you realize how crazy today’s cell phones with 5G would be to someone from 2003.
