Comment: Causal entropic forces

TL;DR

This comment critiques the causal entropy framework, arguing it is state-independent and yields zero entropic force under certain conditions, and highlights its incompleteness in continuous time scenarios.

Contribution

It provides a critical analysis of the causal entropy approach, identifying limitations in its state-independence and continuous time applicability.

Findings

Causal entropy is state-independent in the discussed framework.

Entropic force is zero for state-independent noise in discrete time.

The causal entropy description is incomplete in continuous time.

Abstract

In this comment I argue that the causal entropy proposed in [1] is state-independent and the entropic force is zero for state-independent noise in a discrete time formulation and that the causal entropy description is incomplete in the continuous time case.
