Remember this? A problem we didn't have in automated speech recognition tools until OpenAI decided they were going to do away with alignment (not the kind that so-called "AI safety" people do)? And they're giving us "artificial general intelligence" any day now right?

"We're going to get rid of fact-checkers and replace them with community notes, similar to X, starting in the U.S," Mark Zuckerberg announces

He asserts that "the fact-checkers have just been too politically biased, and have destroyed more trust than they've created, especially in the U.S."

(1) The prevalence of misinformation in society is substantial when properly defined.

(2) Misinformation causally impacts attitudes and behaviors.

Voters are mostly partisans who rationalize, swing voters are often ignorant and voters project their views onto their candidates. But this has always been true! The media was better once, but there was no golden age. Most of their grandparents did not read Walter Lippmann's column.
