Very comprehensive. I can think of a few more:
Transcendant AI: AGI discovers exotic physics beyond human comprehension and ways to transcend physical reality, and largely leaves us alone in our plane of reality. Kind of magical thinking, but this is the canonical explanation for AI friendliness in Iain M. Banks’ Culture series, with the Sublime.
Matrix AI: We’re in a Simulation of “the peak of humanity” and the laws of the Simulation prevent AGI.
Pious AI: AGI adopts one of the major human religions and locks in its values. Vast amounts of superintelligent cognition is devoted to philosophy, apologetics, and rationalization. It could either proclaim itself to be some kind of Messiah, or merely God’s most loyal and capable servant on Earth and beyond.
That last one’s a little Reddit-atheist of me but faith is a very common but underappreciated human value around here. Perhaps to the dismay of atheists, a failed or naïve attempt at CEV converges on religion and we get Pious AI. I know enough otherwise-intelligent and competent adults who believe in young Earth creationism to suspect even superintelligences are not immune to the same confirmation bias and belief in belief.
It’s learned helplessness. People have seen loved ones die and remember they could do nothing to stop it. Past longevity research has not panned out, and people have grown rightfully skeptical about a cure for what has up to this point just been the human condition. Though I suspect they’d gladly take such a cure if one existed.
We also think of death as a great equalizer that allows new (maybe better) people to succeed the old (bad) people (e.g. Supreme Court justices). There will arise tough questions about labor, retirement, marriages, population, and democracy currently solved by death, that our existing political institutions are not remotely ready to answer in its absence.
