I don't think that it means anything to say whether one is in a universe with
an infinite future or not: In an all-universe model there are many universes
which have identical copies of 'you' in them and there is no meaning to saying
which one of these universes 'you' are in.

Of course one could argue that the set of universes that are like 'this' one up
now and go on to be infinte outweigh in some reasonable measure those universes
which go
on to be limited. *Is* that what you have argued? I'd like to see your reasoning
because I suspect this hypothesis to be false. (In fact I suspect it to be
irrelevant, but that's another matter).
