The author has a very self-centered and existential (bordering nihilistic) perspective of the future. He obviously worships at the cult of youth - what ever happened to aging with grace? I suppose this is what passes for European continental scifi - postmodernistic porn from those who do not know the rewards of raising a family. Evolution is instinctive - we are hardwired to desire to pass on our individual genes and memes. We are also a problem solving species - we overcome challenges and seek to progress, not wallow in hedonistic enui.
