Earlier quoted context omitted.
It really was social media. Tell an algorithm to optimize for engagement and it will promote the content causing the most engagement: novelty, conspiracy theory, outrage, surprising "revelations" and all sorts of clickbait. If we removed Twitter, Facebook and Tik Tok and reverted YouTube to the pre-algorithmic (subscription based) era, we'd still have free speech on the internet but probably a lot less bullshit. Note…
Social media (especially short-form ones like Twitter and TikTok) is just a natural evolution of media trends that were already present in society. TV replacing radio/text and tabloid newspapers are just two examples off the top of my head. If Twitter/Facebook/TikTok weren't there, other alternatives would've been there to fill the void.
The particular platform that has these characteristics is arbitrary and beside the point. No one is arguing that Tik Toks particular implementation of a short form engagement optimizing feed is dangerous.
