At some point the amount of localized energy will form a black hole.

The Bekenstein bound says if a volume of space has access to a finite

it is also finite, and that implies Bremermann's limit which says
there is a maximum rate of information that can be processed in that
volume, and it works out to be c^2/h= 1.4*10^50 bits per second per
kilogram of mass/energy. However I think it should be possible, at
least in theory, to extract work out of the expanding universe (see
next paragraph), and if the expansion of the universe is accelerating
then it seems to me the amount of energy you could have access to in
that volume of space could potentially be infinite, not finite.
Suppose you had 2 spools of string coiled in opposite directions
connected by an axle and you extended the 2 strings to cosmological
distances 180 degrees apart from each other. As long as the Dark
Energy force between the atoms in the string that were trying to force
them apart was not stronger than the attractive electromagnetic force
holding the atoms of the string together the string would not expand
as the universe expanded, so there would be a tension on the strings,
so there would be torque on the spool, so the axle would rotate. The
axle could be connected to an electric generator and you'd get useful
work out of it. Of course you'd have to constantly add more
mass-energy in the form of more string to keep it operating, but the
amount of mass per unit length of string would remain constant,
however because the universe is accelerating the amount of energy per
unit length of string you'd get out of it would not remain constant
but would increase asymptotically to infinity. If the theories about
the Big Rip turn out to be true and the acceleration of the universe
is itself accelerating then it should be even easier to extract
infinite energy out of the universe, provided we take care to
continually shorten the string to keep it from breaking. So it would
all just be a simple case of cosmological engineering. What could go
wrong?
And If you have infinite energy then you can perform an infinite
number of calculations, so you could have an infinite number of
thoughts, so you would have no last thought (the definition of death),
so subjectively you would live forever. Of course the objective
universe might have a different opinion on the matter and insist that
everything including you had come to an end, but that hardly matters
because subjectivity is far more important than objectivity; or at
least it is in my opinion.
