The danger of uploading one’s consciousness to a computer without a suicide switch
Let us begin by noticing that justice, as most people presently conceive it, permits or even requires that at least some crimes be punished as far after the fact as is now possible. … Radical life extension would so scramble and confound our normal notions of justice that there’s no telling how future Americans would react to the new reality.
Nuclear war could come tomorrow. Those of us who survive it might spend the rest of our days in misery. But that misery would be relatively short. Radical life extension via mind uploads would seem to risk inconceivably long, possibly endless misery. And this holds even if no future generation deliberately inflicts that misery.
