I think computation is an abstraction, not the reality. Same with math. Reality just is, humans come up with maps and models of it, then mistake the maps for the reality, which often causes distortions and attribution errors across domains. One of those distortions is thinking consciousness has to be computable, when computation is an abstraction, and consciousness is experiential.

But it's a philosophical argument. Nothing supernatural about it either.

You can play that game with any argument. "Consciousness" is just an abstraction, not the reality, which makes people who desperately want humans to be special, attribute it to something beyond reach of any other part of reality. It's an emotional need, placated by a philosophical outlook. Consciousness is just a model or map for a particular part of reality, and ironically focusing on it as somehow being the most important thing, makes you miss reality.

The reality is, we have devices in the real world that have demonstrable, factual capabilities. They're on the spectrum of what we'd call "intelligence". And therefore, it's natural that we compare them to other things that are also on that spectrum. That's every bit as much factual, as anything you've said.

It's just stupid to get so lost in philosophical terminology, that we have to dismiss them as mistaken maps or models. The only people doing that, are hyper focused on how important humans are, and what makes them identifiably different than other parts of reality. It's a mistake that the best philosophers of every age keep making.

Reality is. Consciousness is.. questionable. I have one. You? I don't know, I'm experiencing reality and you seem to have one, but I can never know it.

Computations on the other hand describe reality. And unless human brains somehow escape the physical reality, this description about the latter should surely apply here as well. There are no stronger computational models than a Turing machine, ergo whatever the human brain does (regardless of implementation) should be describable by one.
