There's still e-mail, IMs, weather widgets, mobile banking, turn-by-turn navigation, maps, calculator, camera, photo editor, music players, taxi apps, delivery trackers, guitar tuners, games, and a bunch of other things many non-tech people use on their smartphones every day.

Not to mention, the browser, giving access to everything on the Internet - not just social media. This is doubly important for people on the go, and people who can't afford to also own a laptop or a desktop computer at home (assuming they have one).

Heck, we could keep social media as-is and merely ban likes and engagement-based sorting. That would be sufficient.

It's not the service, it's how the service is designed.
