“Why didn’t Iain take my neuroses into account??”
Yes, why didn't he take the neuroses of normal people into account. Normal people who spend 90% of their day worrying about the acausalrobotgod killing everybody.
Strikes me as they simply have never talked to normal people about immortality like that, even in a post scarcity world, lot of people simply don't feel like it would be worth their time to live forever in that.
Edit:
But one of my hobbies is “oppositional reading” – deliberately interpreting novels counter to the obvious / intended reading. And it’s not so clear to me that the Culture is all it is cracked up to be.
This isn't oppositional reading. This is an often discussed thing in the novels. So much so that the novels have counterarguments for a lot of the regular 'the culture is bad' arguments.
Anyway the article is so bad I wonder how well this person can read.
Edit part 2, can't let things go shouting electronic booo:
Sociopaths
They mention that sociopaths either get a 24/7 drone on them to guard them if they do crimes (more a general criminal thing) or if they are more megalomanic sociopaths they get to run out their desires in a virtual world (Which I assume runs a lot like the modern game Rust, where a subset of the playerbase seems to love to make 14 year old boys cry, going from the yt vids I saw). If this isn't enough, they will need to convince a Mind to help them. Because all large machines in The Culture are intelligent. Good luck with that. Also The Culture is not something like the glitter belt of Revelation Space, where somebody can sign a contract to give away their voting rights or something. So the power of a sociopath is already limited.
not solved alignment
They both have, and it doesn't matter. They have because any mind-equiv mind who goes mad gets destroyed (they literally need to take care of large group of humans or go mad, they have symbiotic relationship with humanity), or if they try to go foom they sublime, in the culture universe, sublimation is inevitable. (Therein also lies the real distopian part, considering sublimation is seen as so amazing that keeping a whole culture away from proven heaven seems like an angle to take, then the deathism also would be an argument, but more like that they let people die without going to heaven (but again, this is not subtext, culture not going poof is seen as very weird, only question is why a Yud-equiv mind doesn't come back to uplift the physical universe)).
A manipulated population
Not subtext, but simply text. Often criticized in various ways. But also a lot of behavior outside of the norm is tolerated, see the lava boat ride (where the only person not tolerated is the one having a 'this is a simulation' break). Or the guy just building a cable system.
Not mentioned:
consent
(This is also why humans are not pets).
A hack can also just be a clever way to use a system in a way it wasnt designed.
Say you put a Ring doorbell on a drone as a perimeter defense thing? A hack. See also the woman who makes bad robots.
It also can be a certain playfulness with tech. Which is why hacker is dead. It cannot survive contact with capitalist forces.
