I think I got my first smartphone when I was 23, I never use them for anything other than calling, youtube, and basic web browsing
My typing speed on a phone is something like 15 wpm, on a computer keyboard it's 110 wpm
The idea of using a smartphone for anything pleasurable (other than youtube) is totally foreign to me
i locked my phone down as hard as i could with grapheneos and only using foss apps from fdroid and also locked off my phones ability to use the gps, and also most of its other camera/microphone/whatever functions without asking me. probably doesnt actually do much but lets me pretend i at least have the slightest semblance of privacy
which in general means that doing anything much more than texting or basic web browsing or taking photos or podcasts (or looking at r*ddit, to my shame) is just way too fucking hard to get past all the barriers ive built for myself so i end up not doing it, and i end up looking like the most massive boomer to everyone around me, especially my partner who gleefully runs a million apps for every website and service imaginable
