The author's concerns would mostly all be ameliorated by logging out of TikTok and never logging back in. They seem to think that "TikTok" and "Society" are synonyms. They are not.
you seem unaware that over 60% (150M) of the US uses tiktok and around 70% of that (100M) are 18-30. it's unclear on the < 18 numbers but likely a significant number.
i don't think it's unreasonable, particularly when she qualifies gen-z, to conflate tiktok and society.
it's really out of hand. the brain rot, beyond just the psych labeling she touches on, is crazy.
Generally it means “deterioration of creative or critical thought capabilities into facile but engaging substitutes for thought” - usually it means something like “taking the algorithm home with you; letting yourself become one with the endless torrent of memes that infinite scroll platforms hand pick and deliver into your brain”
It has definitely slipped into real life, amongst us, persons who don't use TikTok. And I've recently heard therapy talk related to relationships/love coming from a close person who I know for certain that doesn't use TikTok, and she's also in her mid to late-30s (so no zoomer).
