If you've been around the block like I have, you've seen reports about people joining cults to await spaceships, people preaching that the world is about to end &c. It's a staple trope in old New Yorker cartoons, where a bearded dude walks around with a billboard saying "The End is nigh".
The tech world is growing up, and a new internet-native generation has taken over. But everyone is still human, and the same pattern-matching that leads a 19th century Christian to discern when the world is going to end by reading Revelation will lead a 25 year old tech bro steeped in "rationalism" to decide that spicy autocomplete is the first stage of The End of the Human Race. The only difference is the inputs.
