Look, it’s just a convenient term for working scientists to use to categorize a group of people who are not worth listening to at all (in the scientific realm). Quantum physics gets a lot of this because it’s spooky but all fields experience some amount of quackery. Think people who send P=NP proofs to universities, “alternate” historians, flat earthers, and the like.
Imagine if there were coding boot camps that were entirely based on developing a good vibe with the computer, and didn’t involve learning about how to write code at all. People go in, “learn” something, but then they try to get a coding job and fall flat on their face because they don’t actually know anything. This is exactly the state of quantum physics re: the general public. I would guess as a scientist it would get demoralizing.
