I understand your point. But science has also shown us over time that things we thought were magic were actually things we can figure out. Consciousness is definitely up there in that category of us not fully understanding it. So what might seem like magic now, might be well-understood science later.
Not able to provide links at the moment, but there are also examples on the other side of the argument that lead us to think that maybe consciousness isn’t fully tied to physical components. Sure, the brain might interface with senses, consciousness, and other parts to give us the whole experience as a human. But does all of that equate to consciousness? Is the UI of a system the same thing as the user?
