Abstract

Physicist J. Richard Gott has given an argument that, if good, allows one to make accurate predictions for the future longevity of a process, based solely on its present age. We show that there are problems with some of the details of Gott’s argument, but we defend the crucial insight: in many circumstances, the greater the present age of a process, the more likely a longer future duration.
