My generation had Satanic Panic. Parents feared that satan worshipers were ritually abusing children. The stories fed upon themselves. Psychologists got in the business of "recovered memories", now-discredited. Parents saw evidence where there was none, until there were more than ten thousand police reports of ritual abuse. They weren't substantiated.
The Salem witch trials were not an anomaly. We create an enemy in times of peace. We gravitate to a cause.
No, quite the opposite, I'm saying that, given you've said nothing specific about AI x-risk or whatever it is you're concerned about, the post might as well apply to climate change, which is a sign something is off/that you should be more specific since if it could apply to climate change, something is wrong because climate change is obviously a thing we should be worried about, which brings me to my next point:
What makes climate change a reasonable concern where AI x-risk isn't?
