> From my understanding the justification for calling it computation comes down to: we can use the physical system to solve a problem that we would ordinarily approach computationally, therefore it must be computing too. Right?

To me, it feels like the intention of "computation" as used here is to give us a convenient way to describe what the physical system _appears_ to be doing (solving something the only way we know how--computationally) as opposed to saying: the rules of our universe influenced these particles to act in such a way that manifested in something interesting to us (an efficient solution to some problem).

Very interesting to think then if we can leverage physical systems (specifically non-quantum, to make that more interesting) to solve NP problems.
