In a block universe, there are my previous selves and my future
selves, all doing their thing simultaneously (as it were). My past
selves are about as similar to me as my future selves at an equivalent
temporal displacement, but my future selves constitute a memory
superset of my present self while my past selves do not. Therefore, I
don't care if my past selves are wiped out by a giant
trans-block-universe-thingy whereas I do care if my future selves
suffer such a fate.
