In this blog post, we explore the possibility that advances in human technology and intelligence could extend human lifespan indefinitely, and analyze the impact of biological limitations and social factors on this prospect.   Homo Deus and the Possibility of Immortality Humans survive by exerting a more destructive and far-reaching impact on the Earth’s ecosystem than any other life form...

In this blog post, we will examine whether advances in science and technology expand human free will or confine it within the framework created by genetics.   Is destiny predetermined?
