> For animals, we are born with primitive causal models of our bodies we can recurse on to build models of the world in this sense. So as toddlers we learn perception by having an internal 3d model of our bodies -- so we can ascribe distances to our optical measures. If you agree that we evolved such an internal model from some base system that had no such abilities or assumptions, then it follows that evolving programs to do such things is also possible. If you think the base system itself already had such abilities, then you have a bootstrapping problem. > Almost no photographs acquire their state from a function X -> Y, because the sensor state is "radically uncontrolled" in a causal sense. This seems like a bizarre claim to me. A camera is clearly capturing a 2D projection of a 3D world. We can also construct 3D structures from a set of 2D pictures, as we do this all of the time with photogrammetry. It's also clear that we can infer "catness" and "dogness" of subjects despite the fact that these are not strictly defined categories, because we literally did this in our pre-genotyping scientific taxonomies which organized the animal kingdom based on morphology, and this was pretty accurate. It then follows that with enough 2D pictures, one could create a taxonomy of objects based on reconstructed 3D morphology with a high degree of statistical accuracy. I think this demonstrates that your premise is incorrect that there is no "world" that can be modelled only from pictures. Current AI systems are probably only doing a subset of this, finding statistical correlations among morphological features, but that's still a world model IMO, if a bit anemic.
