Agree on this criticism for the difference between humans and pigs, but there too many orders of magnitude of difference between shrimp and human to consider detailed measures of computing power very necesary.
Quantifying empathy is intrinsically hard, because everything begins by postulating (not observing) consciousness in a group of beings, and that is only well grounded for humans. So, at the end, even if you are totally successful in developing a theory of human sentience, for other beings you are extrapolating. Anything beyond solipsism is a leap of faith (unlike you find St. Anselm ontological proof credible).
