Human system differ significantly from evolution. One hot take is that it has a lot to do with how “next steps” in a closed loop are generated. In evolution it is purely stochastic, in human systems it’s not (though this starts to touch on philosophy — free will and all). But I think that actually matters because in extremely high dimensional spaces, if you make a huge random jump your chance of hitting a viable spot is effectively zero given the lifetime of the universe.
This may also have to do with the distinction that Brian Arthur makes between Combinatorial evolution and Darwinian evolution are different
