I wonder how much knowledge can be decoupled from experience, if at all.

If I read thousands of books that explain the details of another civilization in another galaxy, very thoroughly and consistently, but it it just happens to be all made up - did I gain knowledge? More importantly, does what I have in my brain now flip from being fiction to being knowledge if that civilization flipped from not existing to existing? How so, if nothing in my brain, or how I live out the rest of my life, changes in the least, if not a single atom in this galaxy changes (let's ignore that gravity has infinite reach and all that, for the sake of argument)?

If yes, how? What in your definition of knowledge makes that possible?

It also does not have access to any knowledge that isn't public or written down or even not in their training data.

With AI, everyone will be average in no time!

Internet started it, hopefully LLMs will finish it.
