> Growing up in the 80s with no cell phones meant it was much harder to co-ordinate schedules, events, social events etc. No "I'm outside, where are you?"

I disagree with this, the lack of cellphones meant that once people agreed to a plan, they stuck to the plan. "Meet next Saturday at 17:00 at the main square", and everybody would be there.

Nowadays people keep arguing and changing plans until the very last minute, it's exhausting.
