@DI. I will assume the gist of your post is:
Computers are not conscious so logic gates can't produce consciousness. Neurons are like logic gates so brains can't produce consciousness, at least not via their neurons in any reductionistic sort of way.
No, that's not what I said at all. I never claimed that logic gates can't produce consciousness. I merely pointed out that your conclusion that since we see neural activity we should JUMP to the totally unwarranted conclusion that neurons must be producing conscious awareness.
Why should we JUMP to that unwarranted conclusion?

If I have understood DI correctly (which seems unlikely) DI would say the argument really goes the other way, starting with the notion of non-reductive consciousness and ending with the conclusion computers can't be conscious.
I feel totally confident that our current digital computers that are based on a CPU which is really nothing more than an automated ALU could never achieve conscious awareness even if the secular view is true.
If the secular view is true conscious awareness would most likely spring from an analog feedback loop which would require an anolog computer and not a digital computer.
Of course, our brains are indeed analog computers and not digital computers, so that's a big plus for the secular hypothesis to be sure. But it still doesn't come close to solving the problem of awareness and experience.
The question of precisely what is it that is "aware" is still quite mysterious.

(it might be that DI is arguing only that consciousness can't be explaied reductively rather than a computer cannot be programmed to be conscious, but that doesn't seem to alter anything substantially).
Well, it does bring into high relief the question of exactly what complex (i.e. non-reducible) configuration is required to "have an experience" and the question of precisely what it is that is actually having this experience.
You say:

But do we really even have the "where"? If we can't say with certainty what it is that is having an experience, how can we claim to know where this thing is?
Your assumption that experience actually takes place within the physical brain may be a totally wrong guess. There are scientists who are suggesting that our entire reality may be a computer simulation. If that is true, the actual beings who are experiencing this simulation may be totally removed from the actual simulation itself.
Then the guess that experience is actually taking place within the brain turns out to be a totally mistaken guess. A guess that was made based on the assumption that the basis of reality is "material" rather than on the assumption that the basis of reality is a "simulation".
We can't say where experience is actually occurring if we can't even say how it is accomplished.

Anti-scientific types are content to form a superficially plausible argument then sit down do nothing constructive ever again. Failure by their scientific opponents can and will be sneered at. Right up to the point where they finally succeed when the anti-scientist changes position as if they knew it was possible all along. And probably claim credit for predicting it, I shouldn't wonder!
I'm far from anti-scientific. In fact, I totally support science and I have great respect for many scientists. I still consider myself to be a scientist even though I'm retired.
But I do have little respect for over-zealous secularists who have been convinced that science supports a purely secular existence. That is just as unscientific as any religious claim.
Here's what they do:
Has science explained how matter and energy could have come from absolutely nothing? No it hasn't. Yet they act like science has an explanation for this. It doesn't, despite what Lawrence Krauss preaches. That's basically atheistic woo woo being preached in the name of science.
You need at least some preexisting laws of physics or quantum mechanics. And that ain't nutt'in.
In fact, scientists are even proposing eternal inflation and infinitely many universes etc. Again, they are getting at least as weird as any spiritual philosophies. And they need to get that weird to keep their paradigm alive. Otherwise they have a need to explain why the universe is so finely tuned to life to exist.
And that's just get to the point where they have a universe they can begin to discuss.
Then they have life arising from a soup of chemicals. Again, with no explanation of how this actually gets started. Just the claim that "Science will someday explain this".
Then they claim that the the ability to have an experience can be an emergent property of energy/matter brought about by there sheer complexity of highly evolved brains. Again with no explanation of how this actually works. Just the claim that "Science will some day explain this".
Science appears to be in huge debt for explanations.
They claim that
someday they will be able explain how something can to be in the first place.
They claim that
someday they will explain why the laws of nature are so extremely fine-tuned.
They claim that
someday they will explain how life got started by pure random chance in a primordial soup.
They claim that
someday they will explain how a brain can have an experience.
My question is, "How long should I hold my breath waiting for that
someday to come?"
Also, what's so wrong with entertaining other possible scenarios and hypothesis in the mean time?

Sit around doing nothing constructive?
And what do you expect people to do. Sit around waiting for the hopes and dreams of secular atheists to come true?
What if the secular atheists are wrong?
I'd rather consider other possible answers since the secular atheists don't seem to be coming up with any concrete answers in a timely fashion.
