We might not want to live forever (emphases, below, are mine). Libertarian author David Friedman appears to be arguing in a new book (which I will be reviewing in the coming weeks) that the future will be an adapt-or-die type thing:

David Friedman, author of such books as The Machinery of Freedom and Hidden Order: The Economics of Everyday Life, now looks at a variety of technological revolutions that might happen over the next few decades, their implications, and how to deal with them. Topics range from encryption and surveillance through biotechnology and nanotechnology to life extension, mind drugs, virtual reality, and artificial intelligence. One theme of the book is that the future is radically uncertain. Technological changes already begun could lead to more or less privacy than we have ever known, freedom or slavery, effective immortality or the elimination of our species, and radical changes in life, marriage, law, medicine, work, and play. “If it can be done, it will be done,” David Friedman has said. “So the interesting thing to me is not what should you stop but how do you adapt.” We do not know which future will arrive, but it is unlikely to be much like the past. It is worth starting to think about it now.
