As the Facebook generation dies out, so does Facebook. I just don't see it. Meta will have to continue to buy competition and hope that the ad market stays a racket forever. The only reason Meta is still relevant is advertising, just the same as Google. Eventually enough people will realize it for what it's worth: anti-competitive enshittification in order to preserve multi-billion dollar companies that have products and services that suck so bad you'd have a hard time paying people to use if they were startups today.
If Meta hadn’t invested in AI recommendations a while back they would have lost against TikTok big time.
