And again you are wrong, you don't need to be wired directly to the phone for distributed cognition
Unless you're working from a non-standard (or meaningless) definition of "distributed cognition," yes you do. They keyword there is distributed
. You can put fifty different monitors in front of you and wire them to fifty different cameras, but your point of cognition is not distributed to any of those cameras, nor the monitors they are connected to. Your cognition is extended to the cameras through your eyes, the same way you would perceive any ordinary event.
You might as well suggest that contact lenses are a form of cybernetics; at least in that sense you could BEGIN to make a case.
