| Fish tastes like fish because the taste is a categorizing representation of that sensory input. What you can do is today is start with a feature map. We can do that with colors https://imgs.xkcd.com/blag/satfaces_map_1024.png (do you perceive this color as red?) and we can do that with smells https://jameskennedymonash.files.wordpress.com/2014/01/table...
That's a fairly limited representation but words are an incredibly low-bandwidth interface not suitable to exporting this kind of information in high fidelity, so we can't. That does not mean it's conceptually impossible. If you wanted to export subjective experience itself then you'd need the previously mentioned debugging interface. Our brains don't have that built-in, but software does. I.e. a program can dump its entire own state and make it available to others. To me subjective experience seems to be an intermediate representation, deep between inputs and outputs, and due to the various limitations we're bad at communicating it. That doesn't mean there's anything special about it. It is a consequence of compressing inputs into smaller spaces in ways that are useful to that entity. > This isn't about twisting words, some people genuinely believe that everything is conscious with more complex system being more conscious. Anything that interacts with the world will have an internal, idiosyncratic representation of that interaction. Even a rock will have momentarily vibrations traveling through it that carry some information about the world.
One of today's NNs will have a feature layers that roughly correspond to concepts that are of human interest. They're often crude approximations, but it's good enough for some use-cases.
Animal brains just have more of that. So in that sense, sure, it's a continuum. But there's nothing mysterious about it. |
Yes, but why does the fish taste have the taste it does? Hell, try explaining what fish tastes like, without evoking similar tastes.

But a feature map doesn't tell you anything about how the space itself works. If you look at that smell graph, you'll see that it uses comparisons, because it's literally impossible for us to explain what smelling is like without saying "well, it's similar to smelling x". Someone who is born without smell could memorize that chart, understand everything there is about smelling, but he wouldn't actually know what it's like to smell.

We're not just bad at communicating it, but we're bad at understanding it, because our conventional means of measuring things doesn't really work for subjectivity. I'm not saying it's "magical", but it's not certain that we even can potentially build tools to interact with it.
