Why would I care whether the future is full of people like me or not? Is there something inherently better about people like me, such that we should be reproducing instead of the people who currently are?
Evolution depends on the competitive aspect of genetic groups as a means of specification. You can say resisting specification is somehow a morally superior position, but really, it is just a sentimental one. Specification will happen regardless and merging will also happen. When there is enough competition for resources, usually only one species wins out. Being apathetic about becoming a dead branch in the tree of evolution is probably going to have that exact outcome.
