Humans sing. I sing every day, and I don't have any social or financial incentives driving me to do so. I also listen to the radio and other media, still singing.
Do others sing along? Do they sing the songs you've written? I think we lost a lot there. I can't even begin to imagine it. Thankfully singing happy birthday is mandatory - the fight isn't over!
People also still have conversations despite phones. Some even talk all night at the kitchen table. Not everyone, most don't remember how.
