I honestly think it will have to be semi curated and look a lot like a more complex digital version of an encyclopedia.
I mean I think the stupid LLM craze is from trying to make something like that in the vain of the “Hitchhikers Guide” but without having to do the actual work and using autogenerated articles except that makes them prone to being false. The Hitchhikers Guide still had writers and people entering and double checking information.
It can then further link you to related stuff from the web but the wide spread of information is somewhat dead since it’s now the product to be sold and free and easy sharing of it would ruin profit margins.
