"Edward L. Ferman - Best From F&SF, 23rd Edition" - читать интересную книгу автора (Ferman Edward L) Why bother? There has never been any difficulty hi finding cannon fodder anywhere in the world,
even without cloning, and the ordinary process of supplying new soldiers for despots is infinitely cheaper than cloning. More reasonably, it could be argued that the clone of a great human being would retain his genetic equipment and, therefore, would be another great human being of the same kind. In that case, the chief use of cloning would be to reproduce genius. That, I think, would be a waste of time. We are not necessarily going to breed thousands of transcendent geniuses out of an Einstein or thousands of diabolical villains out of a Hitler. After all, a human being is more than his genes. Your clone is the result of your nucleus being placed into a foreign egg cell and the foreign cytoplasm in that egg cell will surely have an effect on the development of the clone. The egg will have to be implanted into a foreign womb and that, too, will have an influence on the development of the organism. Even if a woman were to have one of her somatic nuclei implanted into one of her own egg cells and if she were then to have the egg cell implanted into me womb of her own mother (who, we will assume, is still capable of bearing a child), the new organism will be born into different circumstances and that would have an effect on its personality, too. For instance, suppose you wanted one hundred Isaac Asimovs so that the supply of F&SF essays would never run out. You would then have to ask what it was that made me the kind of writer I am or a writer at all. Was it only my genes? I was brought op in a candy store under a father of the old school who, although he was Jewish, was the living embodiment of the Protestant ethic. My nose was kept to the grindstone until I could no longer remove it Furthermore, I was brought up during the Great Depression and had to find a way of making a livingтАФor I would inherit the candy store, which I desperately didn't want to do. Furthermore, I lived in a time when science fiction magazines, and pulp magazines generally, were going strong, and when a young man could sell clumsily written stories because the demand was greater than the supply. The Isaac Asimov clones, once they grow op, simply won't live in the same social environment I did, won't be subjected to the same pressures, won't have the same opportunities. What's more, when I wrote, I just wroteтАФno one expected anything particular from me. When my clones write, their products will always be compared to the Grand Original and that would discourage and wipe out anyone. The end result will be that though my clones, or some of them, might turn out to be valuable citizens of one kind or another, it would be very unlikely that any one of them would be another Isaac Asimov, and their production would not be worthwhile. Whatever good they might do would not be worth the reduction they would represent in the total gene variability of humanity. Yet cloning would not be totally useless, either. There would be the purely theoretical advantage of studying the development of embryos with known variations in their genes which, except for those variations, would have identical genetic equipment (This would raise serious ethical questions, as all human experimentation does, but that is not the issue at the moment) Then, too, suppose it were possible to learn enough about human embryonic development to guide embryos into all sorts of specialized bypaths that would produce a kind of monster that had a full-sized heart, with all else vestigial, or a full-sized kidney or lung or liver or leg. With just one organ developing, techniques of forced growth (in the laboratory, of course, and not in a human womb) might make development to full size a matter of months only. We can therefore imagine that at birth, every human individual will have scrapings taken from his little toe, thus attaining a few hundred living cells that can be at once frozen for possible eventual use. (This is done at birth, because the younger the cell, the more efficiently it is likely to clone.) These cells could serve as potential organ banks for the future. H the time were to come when an adult found he had a limping heart or fading pancreas or whatever, or if a leg had been lost in an accident or had had to be amputated, then those long-frozen cells would be defrosted and put into action. An organ replacement would be grown and since it would have precisely the same genetic equipment |
