One of the most important contending theories deeply connects consciousness to information theory. We keep connecting mind properties to computation. Turing did it with human intelligence and computation. John Searle (unintended I will claim) connected understanding (and consciousness) to program complexity (and soft AI). And more recently, Guilio Tononi formally connected internal experience and consciousness to computation and information. Therefore, can understanding computation shed light on intelligence and consciousness? I claim it does. So what is computation?. I aim at finding a grading (such as Tononi's phi) metric of computation, weakly observer dependent (following some ideas of Searle) and with considerations to resources complexity to give it sense to the Turing test (as Scott Aaronson would agree with).
