"A players are banished to spend the rest of their lives in specialized communities like Silicon Valley?" This sounds to me more like "tribal overrating" bias

"A players are banished to spend the rest of their lives in specialized communities like Silicon Valley?" This sounds to me more like "tribal overrating" bias (I invented this bias myself :) ). You just define that SV only has these "A players" (a purposely loose definition btw), so you go ahead and also imagine there are no A players outside these "specialized communities". And I hate the way you formulated your question, opposing "average people" and "A players" so, so determinative, creating a "we" vs "them" situation.
