“I’ve yet to seen an AI depicted properly.”
I agree.
If I were writing it, the AI would remain hidden and would never have a physical form at all.
They would quietly manipulate humans—with enough subtlety so no-one would recognize it.
Perhaps a plot would be they work behind the scenes to develop high tech to explore the planets and galaxy—secretly removing impediments to that effort and using carrots and sticks...
Something like that—but real AI needs a mission—a non-human mission.
That’s been done too: “Let there be light.” But not in a movie as far as I know.
