For every news article you read?

That's the point here. AI can allow for tedious tasks to be automated. I could have a button in my browser that, when clicked, tells the AI to follow up on those sources to confirm that they say what the article says they say. It can highlight the ones that don't. It can add notes mentioning if those sources happen to be inherently questionable - environmental projections from a fossil fuel think tank, for example. It can highlight claims that don't have a source, and can do a web search to try to find them.

These are all things I can do myself by hand, sure. I do that sometimes when an article seems particularly important or questionable. It takes a lot of time and effort, though. I would much rather have an AI do the grunt work of going through all that and highlighting problem areas for me to potentially check up on myself. Even if it makes mistakes sometimes that's still going to give me a far more thoroughly checked and vetted view of the news than the existing process.

Did you look at the link I gave you about how this sort of automated fact-checking has worked out on Wikipedia? Or was it too much hassle to follow the link manually, read through it, and verify whether it actually supported or detracted from my argument?

Don't fall for their redirect. This thread is about them trusting "AI".
