Immortality has gone secular. Unhooked from the realm of gods and angels, it’s now the subject of serious investment – both intellectual and financial – by philosophers, scientists and the Silicon Valley set. Several hundred people have already chosen to be ‘cryopreserved’ in preference to simply dying, as they wait for science to catch up and give them a second shot at life. But if we treat death as a problem, what are the ethical implications of the highly speculative ‘solutions’ being mooted?
Of course, we don’t currently have the means of achieving human immortality, nor is it clear that we ever will. But two hypothetical options have so far attracted the most interest and attention: rejuvenation technology, and mind uploading.
