We Will Be Gods: Can Humanity Live Forever?

Musings from the Home PlanetWith the death of Stephen Hawking this week we are reminded of his warning to humanity that we must colonize the universe or face extinction. The reason we must leave Earth is that staying here is too risky for humans. Asteroids, a sudden burst of solar activity, or our own self-destructive behavior threatens the human race at any moment. The idea is that we leave the nest, Earth, and spread out into the universe increasing our survival chances.

This idea was certainly a popular one among Baby Boomers. We grew up with Science Fiction stories about humans populating the universe and eventually evolving into immortal beings. This was a comforting idea for children who grew up in the Cold War era where the fear of sudden nuclear annihilation was constantly lurking in our young minds. Naturally, we looked for ways to overcome that threat. But, is this really the future of humanity or an unrealistic belief system built on an instinctive human desire to defeat death? Is all that is necessary for humans to evolve into gods is to give us enough time?

Elon Musk seems to believe that space travel is the right path for humanity. I don’t doubt he’ll have many volunteers ready to commit themselves to a suicidal flight to Mars. But, why are they volunteering? Is it for adventure or for a mythological future they believe in?

I’m all for adventure and pushing the limits of human achievement, but I wonder at an effort that promises so much about a future we can’t possibly know.
