This seems right to me. A dynamical system can be doing computation if its states are *about something else*. If its states don't represent anything, then it's just dynamically evolving.

I don't get why dynamical systems tend to get treated somehow essentially analogue. Dynamical systems can be both discrete (digital) and continuous (analogue) (and the choice between these depends on a variety (often practical) considerations).

An analog computer is to a dynamical system as a map is to the territory - a representation. But it represents by embodying versions of the relevant dynamics and relations, not via abstract symbols

The other issue, of course, is that nothing is intrinsically about something else. Someone interprets it as something else. So it's not as if there were a distinct category of dynamical systems that "compute".

It's very slick, but I think there's something missing. It always felt to me like he and his detractors were talking past one another. I think they have different conceptions about what, fundamentally, is to be explained. The basic difference of opinion is put nicely by David Wallace here:
Inferential vs. Dynamical Conceptions of Physics
I contrast two possible attitudes towards a given branch of physics: as inferential (i.e., as concerned with an agent's ability to make predictions given finite information), and as dynamical (i.e., a...

Also interesting to think about why some biological dynamical systems do end up with this correspondence/representational relation to a target system. My bet would be based on the good regulator theorem

Ok, so part of the answer seems to be that a dynamical account is about understanding the actual dynamics involved in a behaviour, while an analog computation is about building something that preserves the relevant dynamics but isn’t just the system being modelled

Computation is a degenerate type of #control where the input does not immediately affect the output of the dynamical system, just its internal state.
The change can be #continuous or #discrete and I think it is better to think about control /computation in those terms instead of #analog vs. #digital

This is the crux. If computation is the dynamical evolution of a system whose states are 'about' something, then representation isn't a layer added on top—it's the specific topological way the system maps its environment into its own state space. The 'aboutness' is in the mapping. 🌀📉
