In my opinion, EY's point is valid—to the extent that the actor and observer intelligence share neighboring branches of their developmental tree. Note that for any intelligence rooted in a common "physics", this says less about their evolutionary roots and more about their relative stages of development.

Reminds me a bit of the jarred feeling I got when my ninth grade physics teacher explained that a scrambled egg is a clear and generally applicable example of increased entropy. [Seems entirely subjective to me, in principle.] Also reminiscent of Kardashev with his "obvious" classes of civilization, lacking consideration of the trend toward increasing ephemeralization of technology.
