Z is right, of course. There is in the end no prospect of my walking away from this. A being outside time, with co-adjacent access to all the instants along its own extension, would be able to slip backwards and forwards along the temporal axis, effectively solving the problem of finality and creating a loop of permanence—possibly. How well this strategy would have worked against the actual Dämmerung, the fragmentation and demise of history at the end of things, is an open question. I’ve never been comfortable with looping as a strategy, because it seems to me that when the whole field in which the loop exists is erased, so the loop goes, too. You might argue that since the loop never actually touches the point at which that happens, it never ceases to exist—but experimentally speaking you can’t prove that unless you can step outside the whole process, and whether you can do that is the point of the experiment, creating another and more unwelcome sort of loop. In the abstract, I’m not impressed with this questionable permanence. However, I find it’s much easier to maintain that lofty perspective before someone actually presents you with a time machine on a plate.
