Interview with Nick Bostrom by Jonathan Despres. Go to the Interviews. I have a science background (physics, computational neuroscience, and AI) but my home field is philosophy. My research interests are quite wide-ranging as a visit to my homepage () will reveal. We have been achieving real life extension for more than a thousand years. Ancient Romans lived for circa 23 years. Today, life-expectancy in the world is 64 years. For the past 150 years, best-performance life-expectancy (i.e. life-expectancy in the country where it is highest) has increased at a steady rate of 3 months per year.
