Dead Internet Theory is one of the few "conspiracy" theories I sort of buy, in the sense that it's probably not descriptive of the nature of the current internet, but rather predictive of what it's becoming: https://en.wikipedia.org/wiki/Dead_Internet_theory
And also with less of the whole "they're doing this to manipulate people into believing...things" and more "people want quick and superficial information so that's all that's being produced and since it's easier for machines to produce it than humans, humans will automatically get outcompeted and eventually that's all the internet will be." The internet is becoming a dead mall, filled with the corpses of long abandoned Hot Topics.
