I like to consider the far future; I think things like the Y2038 problem is a
good example. Or, as I like to put it, "numbers are cheap, running out of
numbers is expensive." Sounds like we have enough of a plan that we aren't
completely stuck should it ever become an issue. It might never, of course.
