Earlier quoted context omitted.
Facebook has been primarily displaced by Tiktok, which is considerably more addictive than FB. It's like zonking out in front of cable TV in the olden days, if the cable TV had access to an essentially unlimited content library of short-form dopamine hits, was capable of determining exactly what you like, and showing you exactly that forever.
TikTok, for it's many faults, is at least not ragebait farming. It is distracting junk. Facebook feels more malicious in my mind.
Early Facebook was wholesome as well, relatively speaking. It's the cycle of addiction. The early days of addiction are always nostalgic. It's only later that an addiction starts to produce anger as much as it produces relief. I see no safeguards preventing Tiktok from going down the same path, if not worse.
