These systems aren't intelligent because they're not trying to develop a langford basilisk to put us out of our collective misery.
Edit: the "langford basilisk" is a concept from science fiction of an image that for whatever reason causes damage to the human mind. Usually the conceit is it encodes information the mind can't process resulting in a severe seizure or similar outcome. David Langford explored the idea in some depth starting with a short story called B.L.I.T which is a meditation on terrorism, weapons proliferation, hate, the dangers of rapid scientific discover, and also a Nazi gets pwned
Roko's basilisk is very funny because it's just a version of Pascal's Wager where if you think it's bullshit god just goes "understandable have a nice day" and only punishes you if you believe in it but don't sufficiently obsess about it.
It does have that deistic element to it, but it's primarily solipsistic because they don't want to live in the simulated universe and accept it in its programmed natural laws, they want to escape the simulation because they believe it's all fundamentally unreal.
Very different concept. Lovecraft stuff is "ooh these cosmic higher dimensional beings are so weird they drive men mad!"
A Langford Basilisk is based on the idea that your mind is analogous to a computer and the Basilisk image is visual data that causes an unrecoverable hard crash. There's nothing magical about the image, the problem happens when your brain tries to make sense of what it is seeing.
