For now it looks like death can't be "solved" at all. You may be able to prolong individual human life, even by a lot. But how to solve entropy and the end of an empty, cold universe?

There is even speculation that life is from a certain angle only an effect to accelerate entropy under the umbrella of the Maximum Entropy Production Principle (but I do not remember the source).

So from the standpoint of current knowledge of how nature works this seems to look dire.

I also personally disagree. I do not think that the beautiful chaos of life is strictly preferable to the requiem eternam of death. I'll go when I have to, without hesitation and regrets. It's not the things that terrify us, but our opinion of the things.
