We got a Polaroid 100 color print camera in 1960, took pix. Soon discovered it was messy, expensive, heavy, mostly not worth the trouble compared to the traditional roll film 35mm and Kodak 120 box cameras. Not that great an improvement.
People actually had to think about what they wrote down on paper in decent handwriting, putting it in an envelope, putting a stamp on it, dropping it in mailbox, and waiting a week for a reply.
Or finding a pay phone, or going over to wall or table to pick up the phone, dialing a number that was written down somewhere or in one's memory, and only doing voice communication, live, actually talking to each other.
Nobody writes anything down using good lettering--scribbles at best. Snail mail--almost unknown by the 21st centurites. Finding a phone--in your pocket. Remembering a number--in your contact list. Talking to someone--so last decade. Now texting is it.
Losing or dropping and breaking phone--disaster. Your life is over. And just wait until Kim pops a nuke 200 miles over Iowa. Most of US phone electronics will be BBQ victims.
Yes, modern life seems better. But so much has been lost.
Used to watch Howdy Doody and Kukla, Fran and Ollie on b&w TV in Chicago in 1951. Dialed phone and spoke to Grandma by long distance too. Wrote Xmas cards and put stamps on envelopes. So 20th Century!
