i am not sure I understand. Are you thinking that the hero is in its
We could imagine that the Theory of Everything is given by a
Schroedinger-Dirac like equation applied to the quantum vacuum.
Then we can interpret the work of the hero as a dovetailing on the
solutions of that equation. It would build a quantum multiverse. Yet,
that cannot work.
And Telmo gave the reason. If we are machine (and we are machine if
the hero's emulator can start), then physics is a sum on a continuum
of computational histories, and nobody can write a program simulating
that. Only a person, being generated almost everywhere omega times, in
the deployment can "live" that, from inside. (for some others: omega
is aleph_0, the continuum = 2^aleph_0).
