When you think about it, making fake news is orders of magnitude easier than making real news, the same way that a broken calculator is easier than a correct one.
That said, I'm assuming you also mean fake news which is (A) believable and (B) is tailored for a particular agenda.
More scary: you could target individuals and surround them with a bunch of fake persons that they have no way of differentiating from real ones and slowly push them in a direction of your choosing.
Even more scary: You can tailor each individual's completely unique online universe to dovetail with the equally unique online universes of their IRL social connections / networks so that when they get together again at the holidays or meet for the first time at a bar they both frequent, they have serendipitous conversations about discovering the same hyper-niche thing recently, reinforcing their online conditioning with real-life anchoring.
This could be pervasive through not just online discussion forums, but also online news articles, auto-generated YouTube/TikTok feeds, pages inserted into search results that are custom generated on-demand, conversations on dating apps, etc.
Pretty easy. Probably no additional training is required! You probably would need to just get hold of a foundation model that has no AI safety type training done on it. Then ask it nicely. You could also feed it in context some examples of the fake news you would like. And maybe the style. "Here is a BBC article, write an article that Elon Musk plans to visit a black hole by 2030 in this style".
You could also just use a text editor to write a fake news story, or pay $5 to a freelancer to write it if you're busy. I don't understand why people belive llms fundamentally change anything. Worst case scenario they make you slightly more efficient at your malfeasance, just like they do with legit tasks.
Not just slightly more but likely much more. You can automate the hell out of an automated propaganda bot in a way you could never do with a smoke filled room of $5/day workers.
No, it isn't. This is akin to saying that the truth is relative and lies somewhere between "the Earth is an oblate spheroid" and "the Earth is flat." Perception and perspective varies, sure, but fact exists regardless. Fake news is falsified news built on fabricated fakes, and is not just alternative viewpoints. Do not normalize this.
