Well, one place where Renegades come from is when, having read too much of this kind of disgusting ephemeralist agitprop, and noting that advocating for prohibitions or even prohibitionary attitudes on life extension and its related family of technologies amounts to conspiring to murder everyone, forever, they conclude that while it’s not the common interpretation, it’s not really stretching the Right of Common Defense all that far if they go forth into the greater galaxy and cleanse it preemptively of would-be mass-murdering fuckheads, belike.
(While passing sardonic comments about the stubbornness of ephemeralist death-worshippers when it comes to running away from the unbeing they deify.)
Immortality Immorality: Averted, inverted, mocked, beaten soundly, and left to expire if it wants to so damned much, in much of the Galaxy. The Imperials (and many other transsophont civilizations) are of the opinion that anyone who can’t tell that death is an eo ipso Bad Thing, meaningless, pointless, useless, unjust, unforgivably wasteful, personally destructive, and so on and so forth is an idiot, and the ephemeralist factions that propose that it is good for society and even the individual are substantially worse than that.
Of course, said ephemeralists play it entirely straight, but, well, the trouble with being ideologically committed to death is that given enough time, you will lose the greater argument with people who trend the other way. Demographics are a bitch. Such is… life.
Brain Uploading: Pervasive and universal, just about. The Eldrae, after all, being naturally unaging, find the notion of accidental death rather unpleasant, and so took to this technological advancement with enthusiasm; and, as rabid technophiles, even more so once the other technologies it enables – reinstantiation, mindcasting, forking, gnostic overlays, etc. (unlike a lot of universes, there are no convenient laws preventing you from screwing around with mind-states in all the ways you might expect to be able to) – came along; and now are enthusiastically selling immortality to the entire rest of the Galaxy, or at least everyone they can reach. (And, incidentally, considering governments that ban this sort of thing as, essentially, being morally, if not legally, guilty of the mass murder of everyone who dies in their jurisdiction and would have preferred not to; immortalists vs. ephemeralists is a major galactopolitical issue.)
To the point, in fact, that modern – and thus highly engineered – brains come with the technology (“noetic architecture”) for minds to hop in and out designed right in.
Who Wants To Live Forever?: This is the standard point of view of the ephemeralists. Of course, since none of them are immortal, they don’t really have much standing to judge the issue, and in debate, well, funny how it will always start to suck in another century. Or two. Maybe three.
And the conspicuous lack of immortals lying down to make an end of it all would seem to suggest that any number of people do, in fact, want to live forever. Can’t beat empiricism.
