There seems to be real acrimony over whether a transhumanist future is definitionally a future where humans are more or less extinct. I've always thought we should just refer to whatever humans (voluntarily, uncoerced) choose to become as human, just as american made or american controlled jets are called "american", or in the same way that a human's name doesn't change after all of their cells have renewed.
But you know, I don't think I've ever seen this depicted in science fiction. Seems bad. Humans can't imagine humanity becoming something better. Those who want humanity to become something better are pitted against those who want humanity to survive, as if these causes can't be unified. The language for the synthesis seems not to be exist, or to be denied.
Well, I remember a moment in BLAME! (a manga that's largely aesthetically about the disappearance of heirloom strains of humanity) where someone described Killy as human, even though he later turns out to (also?) be an immortal special safeguard, but they may have just not known that. It's possible the author didn't even know that at that time (I don't think the plot of blame was planned in advance)
