Given that this is an online forum, another advantage is that a conversational trail is left for others to discover. The inferences these types of individuals make are often based on a structure of knowledge and reality that others share, so the most common preconceived and incorrect notions tend to have the most documentation on how to ameliorate the incorrectness (given that these individuals are allowed to state their inferences out loud).
Its a good thread, particularly Exuma's comment, but a memento mori from the root node:
My one word "Source?" meant: "You are adding a new episode of fictional info to a discussion about fictional info."
Even in that fictional world the post was wrong. Even if it was right in some allegorical sense, the simplistic allegory adds nothing. "Mixture of experts is like a group of experts where you pick the right expert to ask a question" isn't some hard-won cross-domain self-taught knowledge. It's something a bright 6th grader would pull off.
The self-taught feeling-stuff-out stuff matters when you're making useful connections that get practical results.
When you're just wiring stuff together online, and the wiring together is meaningless, you're doing nothing and taking the consequences of the negative signals
