Now show how the processing of that information is the following of an energy gradient. Are we talking joules?
It's a non-trivial task to produce such an account even for a basic binary adder circuit. Harder still for a decimal calculator and mind boggling at the level of speaking to Siri and getting an answer. Explaining the course of a river is also beyond such explanation at a detailed practical level. Just because it's hard doesn't mean it's wrong.
Remember the domino logic? That is a way to think of computation as 'following an energy gradient. It could be quantified in Joules, if you like, although such a measure doesn't seem useful. It's the pattern of falling that counts, not the total drop height.
David McC might try to tell you that if you had long enough to think about a problem, you'd always come up with the right answer. Even if you didn't get it right, the wrong answer is still freely chosen.
