The problem with the existence of the Internet is nothing can fizzle out now. Used to be your village idiot who thought the world was flat and the Bible was literal would be isolated by stigma within the limited society where they existed, and isolated by distance from any other village idiots.

Now you can find a community of idiots immediately. It’s just a web search away. The community reinforces itself, meaning no bad idea ever has to die as long as someone on earth still thinks it’s true.
