Just because our subjective time speeds up doesn't seem to imply a lack of
desire to optimize the cosmos for utils. It seems many of us would gladly
undertake the goal of sending colonizing expeditions to other galaxies even
if it took far past our lifetimes for them to arrive (provided all the
normal caveats of our ability to ensure the meaningfulness of the
colonizers' existence if they weren't humans, convergence of their values
with our own, etc.). I don't see why a sped-up civilization wouldn't do the
same. Subjective time might be sped up, but they can still attempt to
optimize the future. If they're undertaking speed-up at nanoscales, it's
also likely they have enough control that their lifetimes are vastly
extended in subjective time, if not longer than 100 years of our time.
Colonizing stars in our galaxy could be done many times in a lifetime.
