The point the game makes repeatedly is that consciousness is an emergent property. It is simply a hallucination created by brain chemistry and neural synapses.

What people often misunderstand about the "coin toss" is that they assume consciousness must be some metaphysical concept tied to a physical body, when in reality it's a framework of identity grounded in the continuity of mental states.

There is no "original" or "copy" when a branching process like the brain scan occurs. Both are subjectively valid continuations, diverging only after the moment of duplication. The metaphor reflects the uncertainty from a first-person perspective. It's not about whether a copy was made, but which version you'll continue being.

Personal identity is tied to the continuity of mental states, not to physical substrates. In a deterministic process of mind copying, the coin toss is a matter of perspective rather than chance. The 50/50 is merely the ambiguity of which version will carry on your stream of consciousness.
