Computation is fully explicable as an abstraction over moving electricity around and producing heat. Without a specific theory of computation understanding the CPU isn't impossible but it may prove intractable in the same fashion as its very difficult but not impossible to understand chemistry solely in terms of physics. What is missing would not be a magical compute field but the necessary abstractions.
