My whole point is that you have to trust people, that this is the only thing you can rely on for almost every important thing you care about. For food, for example, I don't eat from sketchy restaurants, unless I get some personal recommendations from friends about it. That is, I only eat from places where I think I have some reason to trust that the food is sanitary.

Also, I didn't say you need to access high quality sources for everything, I again kind of said the opposite: you choose who to trust for what, and that's that. There is nothing more, and has never been anything more, that you can do. Sometimes people and sources you trust will still lie to you, or be wrong, and you'll know wrong information - this is also unavoidable.

Of course, the more important some information is to you, the more effort you should actually spend trying to verify with multiple trusted sources. Some weird fact about cats you saw in a TikTok? Fine to just believe it. Trying to figure out who to vote for, or if the elections were stolen? Probably worth checking a few more sources. Read some definition for a word on Wikipedia, or some old historical event? Probably fine. Reading about an even slightly controversial topic? Check the actual sources, don't trust the snapshot you happen to see*.

Of course, the way LLMs work is antithetical to this, as information provided directly by the LLM is not coming from any human source you can decide if you should trust or not. So you shouldn't trust it for anything important, unless you can verify. But for information or disinformation on the web, nothing has changed, except maybe the quantities.

*for a silly example: the exact definition of the word "electrocution" is a slightly controversial topic - whether electrocution refers to any (significant) injury caused by electricity, or only death. Pedants soemwaht regularly edit the article on Wikipedia to remove the "or serious injury" part of the definition, despite it carrying a link to the OED that includes this mention.
