If you look at 70s SF you get closer to the real 2020s.
AI taking over the world: Colossus: The Forbin Project
An Infectious agent causing problems: The Andromeda Strain
Human pollution causing massive issues: Soylent Green
in science fiction the AI that takes over the world is sapient. usually as intelligent as a person if not more. reality is dumber. we’re just trying to surrender the world to a series of algorithms that can’t tell how many fingers there are in a hand or which way they bend, or what a fucking fire hydrant looks like.
That is in movies and books.
In the real world the turning test is not proof that an artificial system is sentient but only if/when a human thinks it is. It is not about the intelligence/sentience of the system but the intelligence of the human observing that means the test is passed.
Sadly, for large parts of humanity, text based LLMs have already passed the turning test…
