Intrinsic Reward, Biological Utility, and Saving the Planet

Rational choice theory, and in particular its basis in utility theory, is fundamentally unscientific.

He presents a substitute for the utility function, where the agent tries to maximize what it learns about its environment. He shows a similarity to Friston’s free-energy principle, which uses a similar entropic quantity to describe the behavior of any living organism.

Towards Biological Utility

My overall takeaway is that we need to replace the concept of utility with something grounded in biology. It seems like a more satisfying and realistic model than utility theory, which allows specifying arbitrary utility functions.
