This is a strange comment. The author claims to be a human—"what we've done", "we built something", "we pointed a metal box into the dark"—but nearly every sentence sounds distinctly AI-writen.

(Examples: "I keep coming back to this:", "Voyager isn't ... It's ...", "the assumption that the future would exist and might care", "on our doorstep", "see the end of the story", "depends less on ... and more on ...", etc.)
