Why Special Relativity Prevents Copying Conscious States

I was honored to be asked by Kenneth Augustyn to present to the 3rd Workshop on Biological Mentality on Jan. 6, 2020.  The talk was entitled, “Why Mind Uploading, Brain Copying, and Conscious Computers Are Impossible.”  While the talk addressed work in my earlier papers, it offers a clearer argument explaining why Special Relativity prevents the existence of physical copies of conscious states -- specifically, why two instances of physical copies of conscious states located at different points in spacetime, whether spacelike or timelike, would require either superluminal or backward causation.  I also show that because conscious states cannot be copied or repeated, consciousness cannot be algorithmic and cannot be created by a digital computer.  I mention some possible explanatory hypotheses, several of which are related to quantum mechanics, such as Quantum No-Cloning.  Finally, I touch on my related work of whether conscious states are history dependent.

This 36-minute video is probably my clearest video explanation so far as to why mind uploading and conscious computers are inconsistent with Special Relativity.
