None of this is new. At all. The echo chamber is just louder now. Plato and Aristotle were obsessed with this shit, and they are the two most widely-read voices from antiquity. This is literally the value of a "liberal arts education" (small l liberal unrelated to the right / left spectrum). Philosophers have been writing about this stuff in similar terms since writing was invented, and probably talking about it before that.
More modern philosophers have written more approachable versions, but the ideas are as old as we as a species can remember.
