The other Bill Joy, however, would very much like to prevent the inevitable from happening. Four years ago in an article he wrote for Wired magazine, Joy declared that the headlong race in biotechnology and nanotechnology might prove catastrophic. In the time since, he has continued to explore and advance this concern. Joy says he thinks the probability of a ''civilization-changing event'' is most likely in the double digits, perhaps as high as 50 percent.
I'm not as smart as Joy (ok, very few people are), so it's nice to have someone like him with my cheerful perspective on life.
