I think you can apply the same reasoning to show you will be not only the

only sentient being, but ultimately, the only *thing* in the universe (is

this the same as saying you will ultimately become the universe?). If QTI is

true, your consciousness will survive until the end of time in some branch

of the MW with Pr=1. The Pr that any subset of the current universe

(excluding you) will survive in the same branch as you is <1, so as eternity

approaches, the Pr that anything other than you survives approaches zero.

This is true even of the substructure sustaining you, since there is a

nonzero Pr that you will find some other means of sustenance in the future.

It is also true of your toys, that you might use to reconstruct happier

times. The *only* thing guaranteed to survive indefinitely is you bare

consciousness.
