You've made multiple comments saying "otherwise smart people" are revealed to be momentarily non-smart when it comes to believing in materialism and that, oh well, "none of us are perfect". Even if you disagree with materialism, calling a material view of consciousness "dumb" and incompatible with intelligent thinking just seems petty, obstinate, and extremely arrogant.
You said that emergence of consciousness ignores the hard problem of consciousness, which isn't necessarily true at all. Consciousness could be an emergent property of physical matter and there could still be a hard problem of consciousness. Some believe there is no real hard problem of consciousness, but that's another matter.
You said that "otherwise very smart people who assume that consciousness is just an emergent property of physical matter", as if this is something they haven't thought about very carefully for decades, and as if this is at all a settled problem. No one on Earth knows exactly how consciousness comes about; not you or them. Acting with certainty that it must be immaterial is just as bad as the inverse.
In science, the burden of proof is on the claim-maker. The logic that "it's dumb to assume that what we currently know about the universe can be responsible for anything we see in the universe" is backwards. The onus is on you or others to suggest what else there may be beyond the physical universe. Otherwise, yes, we should assume that consciousness is an emergent property as a default position, until we learn about some other mechanism which it could possibly result from.
>It may be that there is some fundamental limit that prevents us conscious beings from grasping the nature of consciousness - and that's if there is anything to grasp in the first place. Maybe consciousness is essentially axiomatic and irreducible.
It may be. Or it may not be. What is your evidence for, or theory of, how it may not be? Also, even if it were essentially axiomatic and irreducible, how would that necessarily make it incompatible with physics and a material, physical universe? Both could be true.
>to assume that everything about reality is accessible to scientific inquiry and/or physical explanation is dogmatic, unscientific
I think this is using the wrong language. It's not a matter of "assume", but a matter of abiding by the scientific method. No, I don't assume that science can explain absolutely everything in the universe, but if you think it can't, there needs to be a theory or evidence of why. If there is no reason to think you can't, then the onus is on you to come up with reasons. Instead of saying "assume", you should say the null hypothesis. At this time, the null hypothesis is that everything in the universe, including animal consciousness, is entirely physical in nature. The null hypothesis may be beaten by an alternative hypothesis at some point, but so far, there are no testable alternative hypotheses that I know of.
You could say "to assume that scientific inquiry can accurately say anything about the existence of ghosts is dogmatic and unscientific". You could say it about God or ESP as well. But, again, it's reverse logic. What's scientific is following the scientific method: coming up with testable hypotheses, and testing them. If you aren't doing that, or can't, then you're the one acting unscientifically. You shouldn't assume that science can say anything about these things, but until you provide theories or evidence that 1) these things may exist, and 2) science can't say anything about them, then you shouldn't assume the opposite, either. You should remain completely agnostic, but default to the null hypothesis. Defaulting to the null hypothesis isn't the same thing as assuming the null hypothesis is true. Maybe for some philosophical definition of the word "assume", but not the way we use it in typical day-to-day activity.
As for the actual claim itself: at this time, there is much evidence pointing in the direction that it's likely emergent, and zero evidence pointing in the direction of any sort of non-material explanation for consciousness or anything else in the universe. There is currently zero evidence of any sort of non-materialness to any aspect of the universe, and no testable theory for finding any. Believing with certainty or near-certainty that materialism must be false, or that belief in materialism is ridiculous, with no alternative theory proposed or evidence presented, is unscientific.
If your posts on the matter were simply pointing out that the true cause of consciousness is not known and that there are other possible options, that's perfectly fine, but you appear to be treating this as an issue of dogma which only idiots wouldn't accept. I agree that the article should not have listed consciousness as an emergent property as if it were an established matter of fact, but you're basically doing the same thing.
