The worst part of the idea of waiting for the universe to get cold is 
that is is already pretty damn cold. The average background temperature 
of the universe is the same as the temperature of a blackbody radiating 
at CMB frequencies or approximate 2.725 K or less than 3 degrees above 
absolute zero. Stars and other radiative matter make up less than 5% of 
the mass of the universe and as such, they do not raise the temperature 
of the universe significantly above the CMB background. Since the 
thermodynamic energy available for work depends on temperature 
differences and heat exchange, it seems to stupid waiting until the 
stars die out to make hay.
