Worthwhile to note that “TikTok” here just means the format, not the platform. YouTube has its “shorts”, Facebook, insta, X, et all engage heavily in milking your doom scrolled eyeballs for time and profit.
Yes, they don't even mention TikTok from the actual paper. It's a short form video app they custom created.
It is a proprietary eponym.
I uninstalled basically all of these EXCEPT youtube, and that's what I struggle with sometimes now. I find so much great long- and medium-form content on Youtube that I want to keep it around. But I have to admit that I can sometimes fall down a time-wasting rabbit hole with shorts.
The Youtube app now has a "shorts feed limit" under "time management" that will limit your access to the auto-scroll shorts feed to a certain amount per day. Worth checking out!
