here) raised questions relevant to:
Poul Anderson's works of fantasy;
any sf about AIs;
two concepts in Anderson's Genesis;
Anderson's The Rebel Worlds;
his short story, "Symmetry."
Other sf is also relevant. In the Star Trek films, a Vulcan, before physical death, transmits a katra, i.e., a telepathic record of his memories and personality, into someone else. We are not told what usually happens with katras because that is not relevant to the story. However, Spock's katra is reinserted into his revived and rejuvenated body. It is important not to say "soul" because, if immortal souls do exist and if Vulcans or human-Vulcan hybrids have them, then souls are different from katras and Spock's soul is now in the hereafter or en route to reincarnation in another body! Life is complicated; death more so.
