I would agree that we have a lot of fake stuff all over the internet, but it's heavily mixed. I don't know about 70-90%, but maybe the 80-20 rule is in terms of attention rather than actual volume of content; that, I believe already.

The MSM, including the tech giants de facto, push a narrative that keeps the people atomized and out of close knit community, because friendship is the opposite of tyranny. Brother against brother, father against son: if they can divide us, they will, because that makes us weak, and a weak proletariat is a controllable one.

The solution is real, in-person community. They can't fake human interaction.
