It’s an odd premise, for sure. Pontypool is a book, later adapted into a movie about zombies. It’s apparently a metaphor about language, which is especially apt with social media:
AMPS is transferred through language and the only way to stop its spread is to outlaw communication.
Kind of reminds me of Snow Crash. Definitely reminds me of Scott Adams, who insists that humans are moist, programmable robots. But it’s interesting that the book predates social media.
