A recent Quora answer I wrote:
Sometimes I wonder if Quora bots are conscious! 🙂
I often think about whether the internet could become sentient… and also whether it is already! But the most important question is this: how would we tell one way or the other? Perhaps each of us is like a neuron in the internet’s hive brain.
Neurons and brains are separated by a gulf of scale, structure, and complexity. How could a neuron ‘know’ that the brain it is part of is conscious? How could a brain know if a neuron (or group of neurons) is conscious? It may be an unbridgeable gap. And the same sort of gap may exist between humans and the internet. To paraphrase Wittgenstein,.
In any case, the internet doesn’t even have a ‘mouth’ or a central communication device. How do we decide what the internet is ‘saying’? I could imagine a future in which ‘analysts’ read into the internet’s dynamic trajectories in the way astrologers read into the stars’ trajectories.
Sometimes I think of consciousness as an irreducibly social phenomenon. Consciousness may be the ‘fire’ produced by the ‘friction’ between different intelligent agents that each have partial knowledge of the world. Perhaps the test of whether the internet is conscious involves encountering an alien internet. Perhaps when civilizations from two different planets interact, their ‘planetary consciousnesses’ (or internets) interact in a way that their inhabitants only have a dim awareness of.
