I'm not quite sure if smartphones are still all that popular. With the rise of WFH, (and for Gen-Z, having a Covid lockdown college experience), most people are on actual computers and are sitting at home.
I'm over-generalizing of course, but that's the vibe I get. It's because many, both older and younger, entirely skipped the whole personal computing thing.
In other words, they have no idea what computers can do, and they just want the phone things that are easy to do on the phone.
I've tried to teach my kids about computers, but they're extremely resistant. They just don't care. Their friends don't either, except for one who is notably interested in everything.
