I don’t really care if humans will exist in the future. I do care about the humans that will exist, leaving them with a habitable earth. But besides that what do I care about the survival of the human species? I don’t see why people contributing to the survival of humans should be rewarded. I do see that people with a child need more flexibility because it’s hard to care for a child and because I have empathy I support more flexibility and support for them. But why does the flexibility for those people imply inflexibility for others? I’m fine with being ‘selfish’. I want to have a good life, don’t you?
