The Frankenstein fear of reproductive engineering so far has been the future possibility that women could have babies without men, rendering males obsolete. But now scientists are working on making ordinary cells function as eggs, so that they can be fertilized by sperm. They have already made this work with baby mice.
So maybe women, with the further invention of artificial wombs, will become obsolete instead. Not only that, this new technology, should it work, would allow two men to conceive a child. If we get rid of either women or men, same-sex marriage might be the only kind left. Perhaps the fluid gender movement is a preparation for the time when human beings will have no gender and no sex at all!
