There are some other advantages to self-publishing, both of which surpass anything available to species in the wild.
First, you can make changes in your book even after it is published. I haven’t tried this, but I assume what you would have to do is to take down your original book from Kindle, and replace it with files with the appropriate changes. Or updates. Your book would therefore never go out of date. In nature, once seeds have been dispersed, they cannot be called back. A tree might be able to make slight alterations in the structure of the seeds from one year to the next, but not much.
Second, your book will never go out of print so long as there are at least a couple of people buying it. Amazon has always provided this service to the community of readers. If a used copy of a book can be found anywhere, you can find it on Amazon, which links to the book stores or individuals who have these rare items. In nature, seeds eventually die.
My books, including the Kindle books that do not exist in print form, are my legacy to the future, aside from a little bit of money and a lot of love for my kids. After I have died, the only thing anyone in the world will know about me, apart from increasingly faded memories, will be my books. Somebody who does not know me might buy a copy of Rima and find out what I have learned about rain forests, for example. My legacy will also include my website, which, if the host gets paid, does not itself know whether I am alive or not.
Alas, Kindle books cannot be exactly what the author would want them to be. You have to be careful with non-standard text. I read T. C. Boyle’s Tortilla Curtain, in which he inserted some lines in Spanish. Spanish questions end with a question mark, but also begin with an inverted question mark. Boyle correctly included the inverted question mark. But Kindle always inserted a nothing-symbol (a zero with a slash through it) just before the inverted question mark.
In particular, illustrations tend to be extremely messed up in Kindle books. Every kindle book I have read, by other authors, have incomprehensible illustrations. My four Kindle novels have only one image in the book itself (not counting the cover, which is usually pretty good) and that is my author photo. No matter what I do, Kindle inserts it sideways. I can just pretend that it is because I am an avant-garde tradition-breaker.
But even with these faults, a website or a Kindle book (or any other book) is a better remnant to leave for future generations than a gravestone which can be fancy even for the meanest sons-of-bitches who ever lived. A good book, however, cannot be faked.
I will mention for the readers of this religion blog that, alas, this is the only kind of eternity that a person can expect.
