Rodents aren't functions though?

Every computable system, even stateful systems, can be reformulated as a function.

If IO can be functional, I don't see why mice can't.

Well, that's a strong claim of equivalence between computationable models and realty.

The consensual view is rather that no map is matching fully the territory, or said otherwise the territory includes ontological components that exceeds even the most sophisticated map that can be ever built.

I believe the consensus view is that physics is computable.

Thanks. I think the original point about the word 'trained' being contentious still stands, as evidenced by this thread :)

So you think a rodent is a function?

I think that I am a function.
