> Algorithmic content from random creators is not a model for creating an enduring user base. Users will eventually get desensitised to it and leave. There's a limit to how many memes you can consume.

Another thing about these users in this specific demographic always eventually do is they just grow out of it and leave for something else. Or perhaps what was 'hot' in 2020 is now 'not' in 2021.

They'll just flock to the next social network rocket ship until either it runs out of fuel or if the liftoff (momentum) is too slow. Which ever event happens, it's the beginning of the death of the social network's growth.
