We're accustomed to thinking of ourselves as atomic, indivisible entities. I am me, and you are you, and that’s that. I’m coming to see that this is only approximate.

And as we offload more of our sensory and cognitive apparatus to a distributed digital armamentum, we share more of that apparatus with others. How long until the world mind?
