Feel free to do further research on your own if you’re interested. Philosophy is one of my hobbies and consciousness one of my fascinations. Respectfully, doing “research” by skimming the wikipedia article would be a waste of our time; as would responding to any particular definition and arguing over the individual words people have used in summaries of the topic. So I’ll skip that phase of the convo. The fundamental problem with measuring consciousness is that it’s an internal state (a “qualia”*). It is fundamentally an experience, something that exists only as a concept in your mind. This makes it immeasurable. That’s quite the claim, so I’ll provide a smaller concrete example: color. Obviously you can measure the frequency of a photon and say “ah yes, 700nm, that photon is red”. But strictly speaking, the photon isn’t red, it just causes you to percieve “red”; it has a wavelength which triggers your eyes and brain to produce the subjective experience of the color red. That subjective experience of color is a qualia, and it is not directly measurable; at best you can measure the phenomenon that causes that qualia in you, and assume that that phenomenon would cause the same qualia in someone else when they percieve that photon. Technically, you can’t be sure that this assumption is true-- this leads to the “Inverted Spectrum” thought experiment (another great wiki page if you prefer their explanations to mine), where someone’s subjective experience of color as it relates to the frequency of light could be entirely different to your own. Anyways, you cannot prove the existence of nonexistence of such an internal experience, and consciousness belongs to this category of qualia. You know that you are conscious because you experience being conscious, not because you can prove it by looking at what you do. You can’t even be sure that I’m conscious, even if you met me in real life; you can’t prove that I am actually thinking, feeling, understanding, knowing, or realizing anything, because you cannot be me. You can only assume that I am doing those things because you observe me doing stuff in physical reality that’s consistent with the way the only entity you can be sure is conscious (you) is acting, and assuming that since I’m made of the same stuff as you and I act kind of like you do that I am probably conscious. If you could actually prove that it is impossible for a machine to be conscious without that same argument applying to humans, then the philosophy community of the last several millenia would praise you as their messiah. I am interested to see what your argument would be if you want to give it a shot though-- no harm in trying. * Like “data”/“datum”, technically the singular form is “quale”, but I’m gonna be real, nobody ever says that. Anyways if you like reading wikipedia pages about philosophy, “qualia” is a good one!
