Q: What are necessary criteria for existence?
For instance,
-
If your brain was uploaded to a computer, would that count as continuing to exist? (Assuming that the functions of the neurons were faithfully replicated.)
-
What if you cryogenically froze your brain and then 100 years later some nanotech was able to repair your brain, recover the mental state of your brain. Would this count as existing?
-
What if there was a teleporting machine that cloned you and then destroyed the copy of you at the old location. Would you use this teleporter? And, would you still exist after using this teleporter?
-
Does progeny count as continuing existing?
-
Freezing your brain and later repairing it would be fine, as long as it can be done reliably, and, e.g., not mess with your values in weird ways.
-
Teleportation is basically just the same as uploading.
-
Uploading seems fine conditional on it being a faithful electronic copy of your brain.
-
Having progeny isnât the same as continuing to exist, but itâs better than nothing. (because it probably means that your values are more likely to be represented in the future of the universe).
