At first I laughed, then got very sad, at the fellow who wants to sign his child up for this. Does this guy have any idea how many usable organs are needed by actual, living people?Hers is a point that deserves amplification. I, for one, advocate that policy in which we assume as the default that people are willing to donate their useful organs post-mortem and that they should have to take the trouble to officially indicate the reverse should they really feel that way. Polls of attitudes on the question suggest this actually should be the default, quite apart from the fact that this simple change would enormously increase the availability of organs urgently needed and undermine a number of ills -- not just the obvious illnesses therapeutically in question but social ills like criminal harvesting, black markets in organs, and so on as well. I believe this is the default in a number of EU countries and that the impact of the change has been positive.
A small and incidental addityional benefit, relevant in the context of this discussion, is that a change in this default would provide an occasion for narcissistic techno-transcendentalists indulging in pseudo-scientific wish-fulfillment fantasizing to contemplate their foolish and selfish assumptions in a critical way at least long enough to sign the form announcing their hostility for the real world and their real peers and their preference for non-existing post-human beings in a non-existing "The Future" built almost entirely out of their irrational fears and appetites.
