Aeon - Hive consciousness 5-15min

New research puts us on the cusp of brain-to-brain communication. Could the next step spell the end of individual minds? ... we’ve moved beyond merely thinking orders at machinery. Now we’re using that machinery to wire living brains together. Last year, a team of European neuroscientists headed by Carles Grau of the University of Barcelona reported a kind of – let’s call it mail-order telepathy – in which the recorded brainwaves of someone thinking a salutation in India were emailed, decoded and implanted into the brains of recipients in Spain and France (where they were perceived as flashes of light). ... 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. ... 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). ... 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.
