It’s a good riff on conspiratorial thinking.
The only part of the premise I’d stick on is the word “rising”.
We definitely live in a specific era of hokum, and how people learn about them. And there are also conspiracy theories that have currency either for the first time or are way more widely-held than other times.
But past eras were undeniably filled-to-the-brim with superstitions and magical thinking.
If someone today is speaking 99% nonsense, in the past there were as many people who could match it, with 99% different nonsense.
It feels a little like comparing the weight of ignorance, or lack of substance, instead of comparing things of substance.
