A problem of certainty in LLM answers.
Gary Marcus & Karl Friston make an important point. In science and in life, the answer to many questions is probabilistic. In psychology (psychometrics) we talk about confidence intervals

very interesting presentation by @laurennross.bsky.social. I agree with the question asked at 57 minutes; @chrisfields38.bsky.social will correct me if I'm wrong. The entire presentation talks about classical, not quantum physics.

@laurennross.bsky.social reminds us of an important distinction between predictions/descriptions/classifications and a scientific explanation. Being able to predict something reliably does not mean we can explain it. Her example - bull's eye rash predicts Lyme, but does not explain it. "

There is a divergence of opinions on substrate neutrality. In @drmichaellevin.bsky.social TAME work, material-independence is vital (for a model of the mind), in @anilseth.bsky.social's view "whatever brains do [function], it is unlikely to be substance neutral"
