That's fair—rereading more closely, their terminology is neutral on the matter. I jumped ahead because typically when I see this brought up that's the main point folks are talking about: since the physical system is 'computing' whatever, then let's get into the limits and capabilities and classifications of the computation etc., skipping over the question of whether it actually should be called 'computation'. It's also just an interesting question imo—so I'd be okay hearing a discussion about it whether the original statement introduced the philosophical quandary or not.
