This idea terrifies me even more than it amuses me. The notion of the long-term influence that could be gained by a network of cooperating Time-Cube-style theorists is enough to give me nightmares.
It seems that many of those scared are those who've learned in a time of knowledge scarcity (it was difficult to find any information at all on any subject. It took at least a trip to a library and some ability to search the index). Today the challenge is to critically navigate in an overdose of information, a lot of it complete rubbish. The hard part is about filtering out, not finding material.
Now what scares me is that, at least in my country, many teachers haven't realised that the times of knowledge scarcity are gone. They tell student that using Wikipedia is cheating, instead of teaching them how to understand and navigate its (wonderful) citation system, to properly assess information quality.
(note: I suspect your comment to be tongue-in-cheek, but I felt like interpreting it 1st degree anyway)
I am worried though about the (further) rise of anti-intellectualism and anti-science. The effects of this should be pretty clear just by reading the news. This does worry me more than the concerns you've described.
My mother is deeply into this stuff, and I have some friends through her who are lovely people aside from the part where they believe in this stuff. They don't make up a large proportion of my Facebook friends, but some of them are very loud about their beliefs.
Now imagine if you don't care a whole lot about this stuff one way or another, you get your shots on schedule because that's what people do, you never considered government conspiracies because the news never mentioned them, and you see the doctor when you get too sick because that's what everybody does. Then you become exposed to all this stuff, written very confidently and seeming to be backed up with solid facts, charismatic people, and high production values.
I think there's a good chance you'd start believing it!
