Because the universe will end at some point, either getting to a point of maximal entropy, or via a big crunch, or some other unknown mechanism.

One could conceivably escape from this by escaping to another universe - if that's possible - but that's just fantasy at this point. As far as we can tell, even if you can live basically forever you will eventually cease to exist, when the universe ceases to be an environment that's conducive to existence.

So it's physically impossible to live forever. A few hundred billion years is probably an upper bound. Not a shabby run, but not forever.

We can "slow down" the "speed" of time using virtual worlds. Also we can split personalities to have many experiences in the same time. That is providing physical laws cannot be altered in the first place. I think galaxy-wide strong AIs will have better ideas then me, so consider the entropy problem solved.

"consider the entropy problem solved"

I'm happy to consider the entropy problem solved if it is solvable. I don't know how to assess the odds of that.

Ah, of course.
