Pebbles have a very small of natural computational power, in that sense. They memorise events, like photon memorise his encounter with an election, by some change of direction. Then, if you add that pebbles interact with water, and can cooperates, yes, in that sense rocks can be “smart”. In that sense, I have already demonstrate that pebbles are very intelligent, and wise. They never asserts stupidities, and nobody has heard a pebble lying for its personal benefits, nor do they hung their fellows. So much more intelligent than the humans. But pebbles do not compute in those simple task, except what I mentioned, they can bounce, and remember in that way, which makes a lot of pebbles capable of accomplishing some task. Here with have the problem to delineate the computability of the environment, which eventually emulates the pebble, and the computability of the pebble. When I say that a rock does not compute, it is a reference to Putnam’s suggestion that all the movement of the rocks part (the electron in the atoms) can be combined to obtained all computations. But that makes no sense, because the computation is in the logical relations, incarnate in a very special way, so that the computational state are related by some relation (the arithmetical one, and the physical one if the computation is entangled to you). That is true in a trivial sense, because with quantum mechanics, even the vacuum is already Turing universal. This is predicted by Mechanism, the closer you look at the possible environment, the closer you look to a universal dovetailing, or to *all* computations, even "the aberrant one” (those inconsistent relatively to your normal histories). Mechanism predict the “many-world appearance” but also that there is a lot of things at the bottom, virtual things of course, but everything is virtual with Mechanism. It is like the question, can apes solve trigonometrical equation? You can say no. But some will show you that the brain of the visual cortex of the apes do solve trigonometrical equation. But of course, the apes is not its brain. With such a confusion, I could say that I have solved the protein enfolding problem, indeed about a billions times everyday, after they emerges from my ribosome. I do that /// naturally! Lol. When talking about subject and object, there is always some ambiguity possible, and caution to take.
