Immortality

Arnold Kling writes "I tell my high school students now that I think there is a good chance that they will be immortal."

I have told my college students the same thing, and will even be discussing this possibility in my upcoming intro micro textbook. (Read this to find out why humans might achieve immortality within 50 years.)

Obviously, immortality would change the world beyond measure. But long before we achieve immortality people will realize that immortality will someday be within our grasp. This expectation alone will radically alter human society.
