In the short term, yes. In the long term ( >10^50 years) no - when the
average distance between adjacent particles is measured in light years, the
idea of building anything complex enough to be alive looks pretty dubious.

My point is simply that it isn't productive to speculate on the terminal
evolution of the universe based on a theory that is almost certainly
incorrect. It is possible that some moderate adjustment of the big
bang/inflation model will make it fit reality, but it is just as likely that
the entire concept will have to be thrown out. If that happens, who knows
what the new parameters will be? Meanwhile, why generate angst over purely
hypothetical events that might happen billions of years in the future?
