Overview
Methods of preserving persons — or just their personalities — include cryopreservation, uploading, and time travel via acceleration to very high speeds.
Cryopreservation
When current medicine can no longer keep someone alive, long-term brain preservation, whether at cryogenic temperatures or through chemical fixation, could preserve the person until future technology is developed to reanimate them.
Lifelogging
Lifelogging
is an alternative or complementary approach to cryopreservation for the purpose of identity preservation.Preserving someone’s continuous lifeloggings, along with their DNA could allow future technology to recreate a similar mind — possibly more similar than how the person naturally changed throughout their biological life.
Uploading
A personality could be uploaded or migrated to a computer as well as being broadcast to the universe so a future ET could reinstantiate them in case an existential risk occurs. Instead of an ET, if one is willing to entertain either faster-than-light travel or non-Euclidean-space travel (e.g. wormholes), it may even be possible that our far-future descendants pick up our broadcasts and reconstruct us.
Time Travel
By travelling at very high speeds, time would slow down for the traveler per Einsteinian Relativity.
