It's going to get a million times worse when this gets automated.
Right now the quantity of disinformation is practically limited by the human capacity to post stuff online, but GPT-3 style automation will remove this limitation, and we will live in a world of all noise, no signal. Our knee-jerk adherence to "free speech" is opening up a dangerous scenario where we are more vulnerable than anyone else to what is effectively a DDOS on our minds.
I explored this topic in more detail in an essay of mine, where I lay out that a world of Anonymity + GPT-3 can undermine free speech by drowning out real human views and opinions with machine-generated, human-looking propaganda. https://jayriverlong.github.io/2020/07/24/gpt3.html
