I wrote an essay for a private journal last year about how the X-Files mainstreamed anti-scientific and anti-government conspiracy thinking and thereby led to the downfall of American democracy in the 21st century. It valorized the fringe, presaged "do your own research" and consistently told us that the skeptic is always wrong, the believer is always vindicated.
It wasn't a bubble of the 90's, it was a prescient blueprint for the 2020s.
