In this account, the reason it appears unique to humans is simply that they're the only parts of the universe we're in contact with which are able to talk about it.
If that's correct, then the capacity for subjective experience is equally possible for a computer—it just needs to have its "pattern of behavior" arranged (i.e. programmed) in such a way that it does things like thinking, self-reflection, goal-formation, and verbalizing.
If you believe what enables those things in human brains is due the abstract functional relations expressed through neurons, it's probably the "abstract functional relation" part that's more significant than the neural substrate, and it could likely be equivalently expressed in silicon.
The difficulty in considering subjective experience/consciousness to be unique to humans is accounting for how/when it manifests in us, since we appear to be comprised of ordinary molecules. The opposing account I give is founded on the idea that subjectivity cannot be created by arranging molecules in particular ways, so it must have already been there. Neither stance is perfectly founded imo.
I don't see why the right arrangement of ordinary molecules can't result in consciousness. I just don't think the arrangement of a computer executing a set of instructions in its registers is such an arrangement.

This is covered by the "hard problem" of consciousness. It is hard because it appears to be by definition something incapable of expression through ordinary physical relations.
Thankfully we don't need to solve the hard problem to say that computers don't have it. But I don't see why consciousness is "by definition something incapable of expression through ordinary physical relations". What definitionally makes consciousness prohibited by the physical world?
"consciousness" is too broad a term—I only mean to refer to the aspect of it dealt with in "the hard problem".
The hard problem deals with the existence of subjectivity itself. All other aspects of consciousness, e.g. "self-awareness" can at least in principle by thought of as producible by some type of system architecture (in the case of self-awareness, the system needs at least two layers, the upper one operating on data which represents the state of the lower one—i.e. it operates on a model of self; a vast simplification, but maybe it clarifies a bit).
But when you try to do the same thing with the existence of subjectivity itself, it doesn't really make sense. It isn't any kind of "system," it's not even a behavior, not something with any kind of state evolving over time, not reducible to separate parts, etc.
The "by definition" part is most clear if you think of subjectivity as "the field of qualia present at any moment"—a concept also sometimes referred to as "immediate experience". Thinking of subjectivity in terms of a qualia field which is "immediately present" to consciousness (i.e. there is no mediation; it is in fact the only thing we're immediately in contact with as conscious subjects), it's easier to see specifically why it has the characteristics listed above which make it not producible by any kind of "system," and all the things we can do by re-arranging physical materials, e.g. molecules, can be described through the concept of a system (something with parts and relations between them and some kind of consistency in behavior).
I absolutely detest that definition of consciousness. It just moves the fuzziness from the word "consciousness" to the phrase "being like something". It means absolutely nothing. Figuring out what the subjective experience of a model is like is about as unquantifiable as it gets.
Acting on an internal state?
Aware you have an internal state and can adjust it internally? Why cant some code do that?
But no, consciousness is not just "acting on an internal state". A toaster acts on an internal state. It is a complex phenomenon in which an internal state, and the environment interact to create an internal state and a subjective experience of that state which is felt by the organism.
This will go down a rabbit hole, and I don't want to engage in a discussion about what consciousness and feelings are, but there is not reason to believe that computers have feelings. And the output of computer language models is not good evidence that they have feelings, particularly those which are trained on the language models of creatures which have feelings (humans). If they were trained on the language of birds, we wouldn't say there's evidence they are afraid of dogs, even if they were to engage in loud chirping when presented with a dog.
I certainly understand that some people think this. I just don't understand what basis anyone has for believing it with certainty.
Anyone with an understanding of the current state of the art of both computer programming, and AI, understand why it's not sentience. The article said "sentience" not "thought", so we don't need to have a working definition of thought in this case.
Sentience is a stronger form of consciousness. Let's take the weaker form, since if you don't have consciousness you certainly don't have sentience. Consciousness is the subjective experience of "being like something". It is "like" something to be me. It is "like" something else to be you. The question is, is it "like" something to be the Google AI. Given we don't believe it is like something to be a laptop running a program, and AI is currently just (over-simplified but essentially) very powerful laptops running programs that have done a LOT of pre-computation to build themselves (basically just a whole lot of math) there is no reason to believe at some point enough math, or enough computing power, leads to consciousness. We did not believe Deep Blue was conscious even though its power exceeded that of a human brain by several orders of magnitude. This is because computational power alone is not the stuff of consciousness.
The same way 100,000 volts of electricity is a difference in magnitude from 1 volt, but not a difference in kind.
