      Of course. The point is that the ergodicity assumptions under the FEP present a disanalogy with life. Many have pointed this out. What I think many have failed to grasp is that this presents no issue over and above the issue of representing life in a finite state space.

      The FEP represents a ‘slice of life,’ so to speak, and at a high degree of abstraction, at that. For its purposes, the ergodicity assumption is a fairly standard idealisation and unproblematic.

      Over and above the high degree of abstraction and the short timescales?

      Life fundamentally involves organizational change (horizontal gene transfer, antiobiotic resistance, learning a language, learning to dance, healing from trauma). I don't see how any of this can be understood under the ergodicity assumption.

      Even on short timescales it doesn't make sense to me (e.g. rapid genetic change in bacteria, rapid alteration of identities in social interactions, etc.)

      Right, but that cannot be a problem over and above the representation of life within a finite state space. The key is novelty. Koutroufinis and Bickhard both have material on the limitations of representing life or cognition within DST.

      Further, if the constitution or boundary of the system in question is dynamic, as it is with whilrlpools, candle flames, and living systems, the FEP cannot represent that. There are many idealisations going on. It isn’t meant to address the nature and behaviour of life or

      cognition down to the level of biophysics. It’s just a very neat and very powerful statistical trick.

      But all these limitations/idealizations seem counter to what's claimed for the theory in most of the publications I've seen

          The paper is outdated, but covers the basics. I will have a new one soon that should, I hope, clear some things up.
