Science fiction author "Gennady Stolyarov" isn't listed in Internet Speculative Fiction Database either, and the book's publisher, "Rational Argumentator Press" has a grand total of *one* publication, and its web presence is a section of Mr. Stolyarov's personal site. So what we're dealing with here is the self-published work by an unpublished crank sci-fi author -- not that there's any dishonor in being an unpublished crank sci-fi author. There's lots of us around.
I peeked inside the book, and what strikes me is that if you squint, this *looks* like a religious tract pitched toward children, right down to the colorful but stiff illustrations. Take a look at the cover, with it's child dressed in a blue oxford shirt, red tie and khaki chinos banishing death. This is peculiar, in a way that I applaud; an image pitched at children by someone so far out of the mainstream that she has no idea what a culturally "normal" child looks like. That's a good thing for the world, although it may not do much for the author's message. It's more important for people with an oddball streak to write books than people who think like everyone else.
This book appears to come out of the same impetus that underlies a lot of religious impulse: rage at the fact we're are going to die. It's a fact we *should* be uncomfortable with. Religion does the most damage when it makes us too comfortable with the prospect of death. The afterlife becomes a make-up session where we can do the things we put off line life like reconciling with estranged loved ones.
Anyone who regards speculation about technological singularity enabling indefinite human life extension as a "promise" is taking far too much comfort in what is, at best, an intriguing idea. But the universe itself has a finite lifespan; any being who could last to the heat death of the universe, or even a single 2 million century "galactic year" would be so far from human that calling it "transhuman" would be like calling ourselves "transprotozoans".
Whether we just disappear after a mere century or so, or survive as something unrecognizable as human, our opportunity to experience the universe as ourselves, as humans, is brief. We should make the most of it, no matter what we plan to leave behind when our human existence is done.
