> Otherwise, most of these questions become trivial when consciousness is considered as a physical, biological process bound to the brain.
If it were trivial, we'd be creating conscious entities via knowhow and will, not the old fashioned (fun) way.
We... need it be said... cannot. We can't even describe what consciousness is in a way it can be measured or analyzed. We can make things that do things, sure. We can even impart some of our own "consciousness" into these doer machines like robots. But we have no useful way of understanding the phenomena we feel and how that might differ from the robot, or a cat, or a bat, or whatever.
> Why is consciousness bound to a person's location? Because their brain is bound inside their skull.
We might as well ask: why is software in a robot the way it is? Because the software is on that CPU in that physical case over there. It's a non-answer and a diversion. Software can be transferred to other hardware, and there are many questions to be had whether software is consciousness, and also what the nature of that consciousness is given that there's clearly a layer of representation (1s and 0s) different than the material reality of the electrons pumping through silicon.
