In one generation, we've extended lifespans (and quality of life) longer than previously imaginable. That's both a tremendous medical achievement and the source of many questions for the future. If we can one day "solve" or slow aging as many scientists believe is possible, how will that complicate the relationship between generations? What does it mean for the concentration of power in institutions like government and businesses that affect our daily life? And what if immortality is achieved faster via another path: by uploading our consciousnesses to the network? Uploading, downloading, copying and preserving human minds far beyond the lifespans we've known for millennia will require us to radically redefine personhood, and all the ethics and social norms that come with it.
