Discussion What everyday technology do you think will disappear completely within the next 20 years?

Tech shifts often feel gradual, but then suddenly something just vanishes. Fax machines, landlines, VHS tapes — all were normal and then gone.

Looking ahead 20 years, what’s around us now that you think will completely disappear? Cars as we know them? Physical cash? Plastic credit cards? Traditional universities?

I think door handles and locks might vanish for some sci fi doors that only open for pre-authenticated users.

Some pet (doggy) doors do this already. They respond only to signals to open/close by electronics in the dog’s collar.

Mine already does this... Granted it still has a lock though.

Those type of doors are commercially available for a while.
