This was always somewhat true due to the prevalence of human trolls and propagandists, but the ability to generate content automatically makes the problem orders of magnitude worse.
In the world of deep fakes and stuff like GPT-3 (which can be used for what amounts to deep fakes for text), any information without clear provenance is worse than worthless. It's a form of pollution whose result is to confuse, misdirect, misinform/disinform, and indoctrinate, and it's impossible to use it for anything legitimate since it's completely unverifiable and could easily be fake.
Right now it's possible to detect deep fakes, but it probably won't be long until the technology is good enough that this is very hard.
Then there's the fact that a lot of people won't even check. People just believe claims in stupid memes and forward them.
Example: a photo of a supposed Denver International Airport mural depicting kids in masks with different flags on them was going around a while back. The claim was that this showed some kind of foreknowledge of COVID-19 going all the way back to the 1990s. Turns out the photo was of a recent painting that was not from DIA. It was totally fake. I've still seen it making the rounds.
I've been predicting that deep fakes will make an appearance this October in the Presidential election. I think there's a really good chance. It'll be at the last minute so nobody has time to perform any analysis or fact check anything.
