A Bright Future: Immortality Within Reach.

A new book by scientist and writer John Hands argues that most existential threats to humankind have a low or negligible probability of coming true, and that there are many reasons to be optimistic about the future. Hands suggests that altruism, creativity, and a convergence of ideas have helped to foster human cooperation, allowing us to evolve from being in tribes to creating global organisations like the United Nations. He also offers cautious optimism about us confronting environmental challenges, and argues that the more we think about these things, the more action we can take.
