Indeed, no good model predicts that a death of one individual result in the cessation of all experiences for everyone else. Not sure what strawman you are fighting here.

Okay, then I've probably misunderstood what definition you meant to give to "exist". The comment you linked talked about reliably predicting future experiences, and I'll reliably not be experiencing a universe after my death -- so doesn't that mean that the universe won't exist if I shared your definition of "exist"?

That conclusion also seemed to me to follow from your complaint about EY's definition involving photons that keep on existing after we no longer get to experience them.

Anyway, whatever confusion I have about the meaning you attempted to communicate, it was an honest one.

I don't see why. A half-decent model would not center on a single person, and the definition given does not say that "future experiences" are those of a specific person. Unless, of course, the model in question strives to describe this person's sensory experience, in which case, yes, you likely stop sensing the universe after you are gone.
