Your excitement is exactly what is dystopian - instead of writing that you are excited for something new to add to our experience, you wrote that it diminishes humanity into insignificance. Maybe you did not mean it that strongly, but that is how I read your statement.
I did not say that it is diminished. Maybe I didn't express myself very well, though. If artificial intelligence takes over the universe, its origins in biological intelligence on planet earth will remain just as important, even more, but will be proportionally insignificant.
