It’s also possible that FAI might necessarily require the ability to form human-like moral relationships, not only with humans but also nature. Such a FAI might not treat the universe as its cosmic endowment, and any von Neumann probes it might send out might remain inconspicuous.

Like the great filter arguments, this would also reduce the probability of “rogue singletons” under the Fermi paradox (and also against oracles, since human morality is unreliable).
