Kipplinger has an article, actually, an annoying slide show, which lists 10 things that will soon disappear forever and 7 things that refuse to die. I still use some of those things that refuse to die, sort of like the Creature from the Black Lagoon.
The penny, I like it; the fax, I pay bills with it and checks, which I use to pay bills, maybe one bill a month, but I still need the checkbook for that. All the rest are paid online. Or by fax. I do use the fax online, I got rid of my home phone, which I only kept all these years for my one or two faxes a montht that I send, but now I use an online fax service and was able to drop the landline at home.
And one thing I’m not happy about losing, my internet privacy.
