The stomach (like any system) is simultaneously performing an energetic transformation of matter and implementing an informational relationship between inputs and outputs; but what we care about is the energetic transformation. If I were to run a simulation of digestion that maintained the same informational relationship between inputs and outputs in my laptop, I would be implementing the same computations but I would not be doing digestion. This is precisely the opposite of what happens with my laptop. What matters is the computation;
