Perhaps the fact that we act like utility monsters to other animals is part of the point.
Also, no snark intended but 'case in point'.
Mmmmm I feel like if that’s what they were going for, they would have stated it explicitly.
Also hahaha wow never realized that malapropism. Leaving as a memento
We can't properly rationalise with a being that derives 100 times more utility than humans any better than we can imagine a fourth spatial dimension, so instead, let's go in the other direction.
What if humans were the beings that derived 100 times the utility? Would we be then be able to justify consuming 100 times the resources?
Well, we can and we do. Case and point, literally any other animal.
That leaves a choice: either one accepts that being a utility monster is actually ok, or refrains from causing harm to any conscious being, human or otherwise.
