My observation is just that the process you're going through here in taking the "I think therefore I am" and making it into the descriptive and testable system is similar to the process others may go through to find the simplest way to have a 'conscious' system. In fact many people would resolve 'conscious' to a very similar kind of system!

I do not think either are impossible to do once you make, shall we say, appropriate executive decisions regarding resolving the ambiguity in "me" or "conscious" into something useful. In fact, I think both are useful problems to look at.
