The focus on consciousness as a guiding beacon and the insistence that consciousness is a indivisible unity is something philosophers made up because they needed something to debate endlessly with no chance of every getting anywhere.
If we define any umbrella term to be indivisible we can have the same pointless masturbation over its unattainable special snowflakeyness.
We acknowledge that a Nation or Computer or Corporation is something consisting of components that can be identified and described with some degree of precision but when it comes to consciousness there's suddenly a refusal to accept that it could be broken down to components only, there have to be some core that's pure consciousness to it despite the fact that we can enumerate components that if removed from a human would reduce him to something that pretty much everyone would agree on is something not conscious. Or do you think a person with no sense of touch, smell, vision, hearing, emotions, no language or object recognition, no motor control, no memory, no planning and executive capability would still be a magical conscious being?
If you do, please tell me what precisely he still have left that is consciousness, and oh, if you name a component that I forgot to remove that's of course not an argument for magical consciousness, it's an argument for my list of subcomponents being incomplete.
And with that out of the way, how come that artificially implementing a component of what we refer to as consciousness isn't actually a step towards artificial consciousness?
