Yea that's something that I thought about when I rewatched Serial Experiments Lain recently. It was made in 1998 and they correctly predicted that in the future the internet was going to become mainstream, but because the only way to access it then was with PCs they also assumed that would mean that everyone would become super interested in computers too and most of the characters have rigs that would put mine to shame. Fascinating how one didn't require the other, which I think would have seemed unbelievable at the time.
