Immortality

 Having exceeded my life expectancy it's natural to think about mortality.* I know of a number of possible ways in which some sort of immortality might be possible (pluralism again):

1. Uploading of one's mind to a computer.** Not available yet.

2. The block universe. "I'll always be alive in the year 2020." (One only needs the block universe model to be valid for the past. Any problem with quantum mechanics influencing the future*** is not an issue here. Once I'm dead my whole life is in the past only.) 

3. The conservation of quantum information. (If the real me is just information, e.g, "I think therefore I am.")

4. Recurrence. Under the right laws of nature if you wait long enough I'll be back.

5. Everett Quantum Mechanics. Any time I die a different copy of me survives. Like Schrodinger's cat. (There wouldn't have to be a single continuous "consciousness.")

6. "The Soul Hypothesis."**** Is the "real me" a wave function, or a quantum field, or ???

7. Metaphysical solipsism. Your mind is the only thing that exists, ever. You're around for just as long as the universe is.

8. If what we are is a network of ideas then recording and preserving those ideas.***** (Related to number 1 above but perhaps without an ongoing active element.)

9. Combinations of various of these.

But once again, extraordinary beliefs require extraordinary evidence. It seems appropriate to publish this on Dia De Los Muertos.

* I've argued against the idea of immortality in my blog of 15 October 2010.

** I laugh at this idea when I think of some of my old computer programs that can not be run on any of the computers that I have today. (Think coding forms, punch cards, and magnetic tapes.) And hardware updates have sometimes forced me to make software changes.
