How does a way of interacting with the environment come to have an experience of any kind, let alone something totally unprecedented and explainable like 'red' or 'pain'. It is like saying that if you begin counting to infinity at some point the number is bound to turn purple. This is a failure of skeptical imagination. I can see exactly the assumption you are making, and understand exactly why you are making it, but can you see that it does not automatically follow that a machine which functions without experience should develop experiential dimensions as magical emergent properties? > > The same goes for more abstract substrates, like bits of information. >> What matters is not the bits, nor even the arrangements of bits per >> se, but rather what is represented by the bits. >> >> "Information" is just a catch-all term for "what is being >> represented".

The data of an mp3 file is interacted with in the same way by a computer whether it is formatted as something we can see or hear, but the computer has no experience of either one. Blindsight also shows that qualia is not an inevitable result of interaction. I agree with what Max said (two years ago!): "Information requires interpretation. The magic isn't in the bits. The magic is in the interpreter." After having been in the opposite camp for many years, I can say that what he is saying is glaringly obvious to me now. There is no atoms, no molecules, no events of any kind without some frame of perception which makes sense of all of the different levels of potential forms and functions which we have been able to detect. The failure of imagination, in my estimation, is to sidestep the issue of perceptual relativity - to presume a naive realism of simple little dots and paths like we might see in a cloud chamber. Without a frame of reference, each of these swirls might be as large as a galaxy, or not visual at all. Atoms could be more like noises or jokes.
