...when brain activity is more stable, consciousness also appears, for unknown reasons)...
This study cannot prove causation. Literally everything we know about consciousness is correlational because it is not something that can be directly measured or manipulated BUT there are very strong correlations that run the other way: manipulating the brain does change consciousness.
This doesn't prove that consciousness is caused by the brain, either. The "brain is mind" camp hasn't ever produced definite answers that it is.
What if the brain is like a switchboard, with the many knobs that are the neurons? What's turning and tuning the knobs? Matter is supposedly unconscious, and so, we're supposedly zombies... right? How can we think, then? Is consciousness an illusion? It can't be, though, because we think and are conscious. We can think about our brains, and can, with sufficient willpower, override the impulses of the brain. So, we must be more than our brains... the question, really, is, what is the nature of consciousness? We know certain things about the brain, but we still know squat about consciousness, and how it works. It's a bizarre mystery. The ghost in the "machine", so to speak.

Again, how do you KNOW they're not conscious? Can you measure it? Right now what you're doing is arbitrarily decided that some subset of activities disqualifies something from being conscious without a single shred of evidence to back this up. If you can find *direct* evidence that a computer is unconscious, I'd love to see it.
How do you know that computers are conscious? Have computers, machines, ever shown a shred of consciousness under close, scrutinized study, by those who are unbiased, and experienced in advanced psychology? I know of no such study that has ever shown that computers, no matter the complexity, are consciousness.
But, why are we, and other known living beings? What sets animals, plants, bacteria and fungi, from computers? Are crystals conscious? They grow. But computers only do stuff when they have electricity. You can turn them off for a year, they can collect dust, you can clean the dust away, and turn them back on, and they'll just keep working, if undamaged. Computers need to be programmed... living beings do not. Is instinct the same as programming? I don't quite agree either way. It is, but it's not quite the same as what we do with computers.

As far as I know, you might not be conscious. After all, from my perspective, your brain is just a squishy machine that blindly reacts to inputss via programming and produce outputs. The science of vision is very clear on this: we can track visual signals as they go in (down the level of individual chemical changes in the eye), travel along the optic nerves, get sent to the thalamus and V1 of the occiptal lobe and processed according to fairly well-understood rules.
Why should I believe that you have a conscious precept of vision, since your visual system is just a computer?
I suspect that we're conflating two differing definitions of "compute". What does it mean to "compute" something? The machines we call "computers"... the innards of a "computer", it's makeup, it vastly different to that of living, biological organisms. We may think that "computers" are complex, but living organisms are vastly more complex. Even the simplest bacterium that science has painstakingly figured out that is, is still vastly complex, and its distinct parts must all be together for said organism to be alive. Any part that is removed will kill said organism.
Not so with "computers". You can replace, and mix and match, different parts of hardware, and even software, and it will just work. Not so with living organisms, at least, not so easily. Organ transplants can be rejected without immune system repressants. "Computers" have no such problem, because they have no hardware that acts as an "immune system".
A complex topic, now I think about it more deeply.

That may be true, but you're the one making the hypothesis, so it's on you to defend it. With evidence.
I posted an article, true. However, those positing that we are machines that react blindly to programming and inputs also must also explain and defend their positions.
It should not be automatically presumed that because there are correlations which seemingly prove to some people that the brain is the source of consciousness, that that is how it is. What if the data can be interpreted differently, to reach another answer that is also valid?
What if "brain is mind" is only part of the answer that is unfairly being given all the attention, blind to other answers?
I do suspect, heavily, from my own experiences, that consciousness is metaphysical. Quantum physics suggests that consciousness is primary to matter, and that conscious awareness has heavy influences on experiments that are done, such as the double slit experiment with photons. Why is it that photons act as particles or waves depending on the observer? Maybe reality isn't as objective or as solid as the materialists conjecture?
Maybe reality is subjective, and heavily dependent on the conscious observer? What if we living organisms, for the most part, share a common reality, and that certain aspects are relative, depending on the consciousness that is observing?
"Brain is mind" is not the final, true answer... it is a possible answer that has, in my opinion, some pretty flimsy, unproven claims behind it.
Again, correlation is not necessarily causation. Just because we can correlate biological activities in certain ways, does not mean that consciousness is caused by the physical body.
