And AI or not, I'm willing to bet AI was used to fact check.

I can imagine right now, all over the place, people are being tasked to write some article or provide some stats. They use an AI to do the work for them, lazy people that they are.

Then, their manager plugs the stats into an AI to fact check...

I remember some movie from the 80s, pre-internet. Anyhow, everyone had an implant, and it was decades in the future, no one could even read or write.

Instead, they'd just go through their day and if they were unsure of the answer to something, the implant would search a database and just fill in the info. From their perspective, they couldn't even tell if "what they knew" was in their head, or provided from the implant.

Anyhow, one guy couldn't get an implant and was considered disabled, for he had to learn to read, and acquire knowledge the old fashioned way. He slowly discovered that if he even tried to show people how to read, they were blocked from learning. And if info was provided contrary to "the public good", people simply couldn't understand the concept.

Turns out, some central computer decided what was right and wrong, and those that created it and perhaps once controlled society died... leaving in in charge.

This is what we saw. We saw someone query their implant, and then fact-checkers query their implant, and OK! All good!

Also, I think there were onions in the movie.

It depends. If you're selling the AI then yes, it will do better fact-checking than any human could do. However, if you're explaining to a client why your AI made up stuff that has costed someone thousands of dollars then no, it was always your employee's job to double check everything.
