Even if the brain is immortal, it is still finite state
given a finite lifespan to the universe.

And no *finite* system can perform an *infinite*
number of computations.
That's because erasures are performed and,
inevitably, the process of computation becomes
irreversible, and produces some entropy, and some heat.
And a *finite* system has not *infinite* energy, or
*infinite* states.
So, *if* consciousness can be reduced to computation,
consciousness can not be eternal.
