Hmm. Really? Few call centres or queuing systems around yet. My bank had a local number that was answered in 3 rings - often by the same person. So did the phone and electric companies, and the tax office. They might actually remember you.
I probably couldn't ping a friend if they were out with the dog, or on holiday, and definitely not in the car - few had mobiles yet, though by the end of the 90s they were getting common enough.
A lot of things were indeed simpler as we've added needless complexity to loads of things. Adding complexity layers seems to be how we solve everything. Even politics was simpler - note I don't say better.
Then again a lot of things were fairly crap - VHS recorders, CRT TV, cassettes.
Computing was much more fun - far many more platforms - SunOS, Amiga, ST, PC, Apple, BeOS, etc, and it was still feasible to know all of the thing. Now it's more likely to be a small part of a much more complex whole, too big for an individual. That speaks of maturing, but also of over-complexity.
Swings and roundabouts really.
