> If AI makes it trivial for the average person to create an effective terrorist movement
How do you imagine this and what exact role AI is going to fill that would make it somehow trivial?
I have trouble imagining that AI would be able to somehow magically do better than my project manager (and she's a good one). Being able to possibly think faster and not needing to sleep won't make any difference, and neither will scaling. Nine doctors won't help a baby to be born in a month.
Buying a bajillion dollar TPU farm to run some hypothetical AI brainwashed with terrorist agenda that'll somehow replace hundreds of propagandists is not trivial. And I don't think it's enough to start a movement.
> floods us with so much propaganda that most information you see is false
This ship had already sailed (one can say, some millennia ago) and it didn't require any recent scientific breakthroughs. Scientific breakthroughs (such as printing press, or radio, or Internet) only improve spread of information, and propaganda saturates available media channels to... uh... comfortable levels. But it'll never reach the "most information" state because that's just illogical (the consumption will stop before that point, just like how no one reads their spam folder today). And there's nothing AI-specific here, humans manage this just fine.
Honestly, I believe AGI won't change a thing, for the same reasons there are still manual workers everywhere despite all the stories how robotics was gonna change the world. The reason is very simple: troll farms are way, way cheaper than computers. Just like a cleaner person is cheaper than a cleaner robot.
Yes, it could be speculated that somehow all those speculated data hoards about us, paired with extreme amounts of processing power could somehow lead to personalized propaganda. I'm very skeptical - I was told the very same story about targeted ads (how they're gonna change my shopping experience and whatever), and despite what Google wants to make everyone believe (because their valuation highly depends on it), I'd say they were a complete failure. I really doubt targeted propaganda will be economically feasible either. This stuff only happens in soft sci-fi stories, where economics and logistics are swept under the rug of our suspension of disbelief.
It's not the AGI we should be afraid of, but a technical progress that will allow AGI to become drastically better than us, puny meatbags, at lower costs. Which is entirely different story.
Oh, and human susceptibility to propaganda and populism of all sorts. Which, again, is not related to AI at all. Unless we should call our politicians artificial intelligence. (Looking at some, maybe we should... Just kidding, of course.)
