Here is an excerpt:
What are the implications of a technology that seems to be converging on the sharing of consciousness?
It would be a lot easier to answer that question if anyone knew what consciousness is. There’s no shortage of theories. The neuroscientist Giulio Tononi at the University of Wisconsin-Madison claims that consciousness reflects the integration of distributed brain functions. A model developed by Ezequiel Morsella, of San Francisco State University, describes it as a mediator between conflicting motor commands. The panpsychics regard it as a basic property of matter – like charge, or mass – and believe that our brains don’t generate the stuff so much as filter it from the ether like some kind of organic spirit-catchers. Neuroscience superstar V S Ramachandran (University of California in San Diego) blames everything on mirror neurons; Princeton’s Michael Graziano – right here in Aeon – describes it as an experiential map.
I think they’re all running a game on us. Their models – right or wrong – describe computation, not awareness. There’s no great mystery to intelligence; it’s easy to see how natural selection would promote flexible problem-solving, the triage of sensory input, the high-grading of relevant data (aka attention).
But why would any of that be self-aware?
If physics is right – if everything ultimately comes down to matter, energy and numbers – then any sufficiently accurate copy of a thing will manifest the characteristics of that thing. Sapience should therefore emerge from any physical structure that replicates the relevant properties of the brain.
