Challenging Neuron Counts as a Proxy for Sentience
The podcast discusses the limitations of using neuron counts as a proxy for sentience. While economists have justified using income as a proxy for welfare despite its flaws, linking neuron counts to intelligence raises ethical concerns. Factors like body size affecting neuron counts and the moral importance of intelligence in assessing value challenge the validity of neuron count proxies. The podcast encourages exploring better alternatives to assess sentience effectively.
