Which old technology do you wish would make a comeback?

Pay phones.
Only I guess you'd use a debit card now.
I know they wouldn't be on every corner like they used to be, but if you end up with your phone drained and your car broke down be nice to have a few here and there in case of emergency.
I suppose it would cost too much money to maintain them though.

Decent hi-fi, not this compressed wifi/bluetooth garbage no matter how good your wireless speakers are.

Glass bottles. Things taste differently in plastic. I’m not a fan.

morse code....some guy in the navy taught it to me ..used it to cheat in school

auto tape decks. used to love my mix tapes.

Drive-in movies.

Disappearing for a couple of hours with no one knowing where you are.

Video stores. I use to like walking through the store and looking at all the movies.

Video discs
