I don’t actually use TikTok or even the “sliding” function on youtube shorts, but I feel like my attention span has gotten much worse after they started getting popular. Even watching a 2 minute video feels dreadfully long, let alone a 10 or 20 minute video, so I end up watching a mostly short animation memes instead.
I started to feel that, and I felt like I was more impatient and irritable. Not claiming this is evidence, just my own intuition. So I don’t watch YT Shorts.
Also no TikTok, Reels, or any other clones of those.
