Yes, I’ve come across a few. In K.W. Jeter’s “The World of Null” the autonomous race called the Gossamer is built entirely from adaptive nanotech that thinks in distributed threads, almost like a living organism. The author treats the nanotech as a character in its own right, with motives and a sense of curiosity that drives the plot. It’s fascinating how the narrative frames the technology’s evolution as a form of consciousness, but I always wonder whether we’re actually getting close to creating something that can truly “think” or if it’s merely a sophisticated simulation. The line between autonomous machinery and sentient being seems to remain a bit of a literary illusion for now.
