Religion is the second of the 3 great social control mechanisms that have governed the development of human society. It was preceded by the standing army and usurped by economic theory.
Social control mechanisms, like forms of media, are never usurped they are simply absorbed in to the ever widening web of hierarchical dominion.
Economic theory is nearly as diverse as religion. As with the plethora of religions, there are nearly as many economic theories as there are economists, and I see no evidence of these theories usurping anything.
thats pretty myopic. you might try reading yuval harari's "Sapiens".
