There has to be some degree of separation at some point though. For all I know, there could be more than one "me" experiencing life as processed by my brain at any given time, but the self cannot possible be the complete interface as a whole. If it were so, then the self could not continue to exist if a portion of the interface were removed, but it can, regardless of it being a less than optimal condition.
