[Question] Thoughts on paper “How Organisms Come to Know the World: Fundamental Limits on Artificial General Intelligence”?

I’ve read the abstract of this paper, How Organisms Come to Know the World: Fundamental Limits on Artificial General Intelligence. It says:

A general example of an affordance is the use of an object in the hands of an agent. We show that it is impossible to predefine a list of such uses. Therefore, they cannot be treated algorithmically. This means that “AI agents” and organisms differ in their ability to leverage new affordances. Only organisms can do this.

This sounds very strange to me. I have basically 0 technical knowledge of AI, just the general ideas I’ve gathered reading in general. But I thought one of the main characteristics of it, is that it learns by itself (or with what we feed them). So, that precisely one does not need to “predifine a list of such uses”, in the context of the abstract. Particularly, self-directed learning AIs are famous for coming up with totally unpredictable ways of achieving their goals. Isn’t it? I guess in the language of the abstract this would mean that they are not treated algorithmically… I don’t think anybody would do such an error and less so, be able to publish it. So, what am I missing?

I searched in LW and the EA forum and I didn’t find any post or comment about this paper, so I thought I would post a question.
