there are no people who are "most knowledgeable.

I agree, 100%

There are people who are really good at lying about it, but no one who actually has actionable knowledge.

Humans like to follow and I don't think people even have to be good liars, all they have to do is sound confident in their viewpoint and you'll see a lot of followers latch on.

I simply try to process as much data as my little brain can handle, weed out as much fact from opinion as I can and try to make the best wild ass guess I can.
