Tree and loop as moments for measurement

Biologically motivated computing presents us with a measurement process in science. It triggers an epistemological shift from state-oriented physics to measurement-oriented physics, in which we can find a parallelism with Wittgenstein's shift from rule following to a language game. We argue here that an approximation or computing process can be viewed as a language game and propose an idea of proto-computing which is metaphorically formalized through disequilibration between tree- and loop-program, as a model for measurement-oriented computing.
