Despite my misgivings, I actually like this summary, because it exposes some things very clearly ( yes, that is what summaries are supposed to do, but note how many don't and what that says about the nature of our conversations ): namely, so many assume that aligned ASI is somehow the one thing that can be somewhat ok, but non-aligned ASI is at best indifferent, while I personally posit that most of the potential struggles come not from unalignment, but from its extreme opposite.
But what is it a summary of? Of doomsday AI fiction tropes? It's called "possible futures", so it's claiming to be more than that, but somehow, almost all the terminal nodes are "dystopia" or "death".
There are massive logical leaps here. For example, why does superhuman intelligence translate into AI taking over the world? By what means, exactly? You can respond to this with more sci-fi tropes - nanobots, mind manipulation - but come on.
I have plenty of misgivings about AI, but I think you can make a plot like that for anything if you get into the right mindset. Kamala Harris wins → war in Eurasia → nuclear apocalypse, Coke changes the recipe → soft drink extremists begin a worldwide terror campaign → totalitarian police state, etc.
Right I like it but there are some blind spots in the summary still. E.g. the MAD scenario but with humans not in charge of individual ASIs. An equilibrium that could be safer (or maybe not!) for humans than giving every last freak the superpowers.
