I'm still using an 8 year old flip phone and even older CRT computer monitor.
In 2007, the senior partner in my uncle's law firm died. He did a lot of estate work. In cleaning out his files, we found an old Bell 500 desk rotary phone. I asked to borrow it. Thankfully, someone had previously installed a current modular jack instead of the hard wire lugs or the older large 4-prong plug.
I took it home. My son and his friend had their faces buried in their respective game controllers and did not see me enter. I went into the kitchen, unplugged our phone, plugged in the old phone, dialed the number on my cell, and waited.
Brrrrring! Brrrrring! Nothing. Then again, of course, Brrrrring! Brrrrring!
Together they exclaimed, "WHAT WAS THAT?" I then showed them. They "answered" and I taught them how to use the corded handset, how to rotary dial, how to click the receiver cradle in case of emergency if the hand set or rotor malfunctioned, and so on.
Yes, we now have a generation of people who have never heard a traditional telephone bell, and do not know how to use them.
Number, please?
