How do we know who is in a bubble? :) When I walk around downtown, I see hundreds of people on their phones, and maybe one or two of them is actually using it as a phone. Obviously I don't know if they're on dating apps specifically, but they are enormously popular, so it seems plausible.

No, they're not. In the country I'm living in, *no one* uses phone calls except for rare things like delivery people calling because the box doesn't fit in your apartment's delivery boxes. Absolutely no one under the age of 50 uses voice calling to talk to their friends or family; they all use LINE texting.

I haven't taken a phone call in over a month now (from the Amazon delivery guy). I use dating and texting apps every day. For actual talking to friends/family, I use voice and video chat functions in chat apps.

Something on that order, yeah. Looking through my phone's call log, I had a call with a friend in mid-August, and another with another friend in mid-July. Prior to that was a call with my mom in April and that's as far back as the log goes.
