I'm aware that you said 30 years ago, but since I'm in my 70's I'll compare my childhood with today.
There was no TV before I was 12 years. The first TV was 9 inches, black and white, with only a few channels and programs.
We had no phone at all until I was in my teens. The phone was in the first floor hallway of our apt bldg. Us kids answered the phone, and then banged on whoever's door was getting the call. Of course, there were no cell phones, cordless phones, or any other hand held gadgets.
There was no airconditioning in homes. During the Summer we went to the movies on Sat. and watched double features, since the movie theaters were airconditioned. Also, there were no thermastats. Heat came up thru radiators; and if you lived on the top floor, as I did, often the heat did not make it up.
Few apt. buildings had elevators. You walked up and down.
There were no computers.
There were few electric gadgets of any kind. There were no microwaves.
Washing machines had wringers that you put the clothes thru. Then you hung them on a line to dry. Our line was on the roof. We had no dishwashers.
I remember the first door I came across at a store, which opened automatically.
Cars had nothing automatic. You opened them with a key. You rolled the windows down. You had no radio, no airconditioning, no automatic transmission. The good part of all that was that many men were able to take it apart, fix it themselves, and put it together again.
We had no jet planes. But that didn't bother us much, since we didn't start to go on a plane until we were grown. I went on my first plane- a prop jet, in 1957.
Most of us had never heard of a cruise ship. Cruise ships were for the very wealthy. It was a way to travel to Europe.
Our family didn't own a camera. Most pictures were taken at a photo studio. I got my first camera when I was a teen. It was big and clumbsy. It had no flash. And it took more than a week to get the film back.
And oh yes, we had typewriters. First they were manual, then years later they were electric.
People wrote letters. A long distance call was too expensive. Cell phones didn't exist. E-mail didn't exist.
There were no charge cards. We used money.
There was no GPS. We used maps.
I think I better stop now. I probably could go on forever. But I'm sure that you can imagine what it must be like to handle all the changes that have come to pass. I on the other hand can not imagine at all what you will be seeing and using 30 years from now. I'd love to stay around and see. Have a great life.
