You know, Stross tacitly considered an interesting form of resurrection in Accelerando--a hypothetical post-singularity (non-Friendly) AI computes a minimum message length version of You based off any surviving records of what you've done or said (plus the baseline prior for how humans work) and instantiates the result.

I'm having real trouble proving that's not more-or-less me, and what's more, that such a resurrection would feel any different from the inside looking back over its memories of my life.
