> plenty of them have all kinds of defects,

Defects that have not rendered them unconscious, as long as they still are alive. You seem not to see the circularity of your argument.

I gave you an example to show that robustness against adverse conditions is NOT the same as internal resiliency. Those defect, as far as we know, are not affecting the origin of consciousness itself. Which is my point.

> How is it a false dichotomy? If you want consciousness to NOT be simulateable, then you need some essential component to our minds that can't be simulated (call it soul or whatever) and for that thing to interface with our physical bodies (obviously).

If you need two things to happen at the same time in sync with each other no matter if they are separated by billions of miles, then you need faster-than-light travel, or some magic [1]; see what I did there?

1. I.e., quantum entanglement

No. Because even if you had solid evidence for the hypothesis that quantum mechanical effects are indispensable in making our brains work (which we don't), then that is still not preventing simulation. You need some uncomputable component, which physics right now neither provides nor predicts.

And fleeing into "we don't know 100% of physics yet" is a bad hypothesis, because we can make very accurate physical predictions already-- you would need our brains to "amplify" some very small gap in our physical understanding, and this does not match with how "robust" the operation of our brain is-- amplifiers, by their very nature, are highly sensitive to disruption or disturbances, but a human can stay conscious even with a particle accelerator firing through his brain.

This makes no sense as written - by definition, there is no concept of "at the same time" for events that are spacelike separated like this. Quantum entanglement allows you to know something about the statistical outcomes of experiments that are carried over a long distance away from you, but that's about it (there's a simpler version, where you can know some facts for certain, but that one actually looks just like classical correlation, so it's not that interesting on its own).

I do get the point that we don't know what we don't know, so that a radical new form of physics, as alien to current physics as quantum entanglement is to classical physics, could exist. But this is an anti-scientific position to take. There's nothing about consciousness that breaks any known law of physics today, so the only logical position is to suppose that consciousness is explainable by current physics. We can't go around positing unknown new physics behind every phenomenon we haven't entirely characterized and understood yet.
