The never-ending academic discussion about "But how do you define relevance?" does not matter. Any simple definition moves you closer to a better one.
Agreed. My point is that the current version of relevance is chosen by Elon for all of us. We should choose our own
You are right, it's just incremental step; might as well lead to more sensationalism incentives and chasing to be the first to 'break" in with their take. Yet, it hints a path; and idea that can be iterated on further. Maybe not by Elon, but that's besides the point.
