Reviewers of the Culture novels tend to project their own political biases onto it. This writer quotes Marx a bit too much. There's some other review where someone was trying to read race and gender issues onto the Culture. They're missing the point.
The Culture novels describe a stable society where the machines are in charge. That's been addressed many times in science fiction, but not, usually, well. Asimov's later robot novels, where it become clear that the robots are manipulating humanity, do address it. That's about as good as it gets. Frank Herbert's Dune has the "Butlerian Jihad", but Herbert's idea of robot social organization is just humans in robot costume. Jack Williamson's "Humanoids" stories, about benign but overprotective robots, reflect someone getting the goal system slightly wrong.
In more popular culture, The Forbin Project (1970), a movie which seems to be enjoying a renaissance, does address the issue. The machines which control the nuclear weapons of both sides get into contact, and agree to take over to keep humanity from destroying itself. They come up with a reasonably sensible plan for running things, which is fleshed out more in the books.
The Star [Trek|Wars|Gate] universe never really addresses this directly, since it would undermine the show's stars. Nor does the Marvel universe; AIs appear, but are not in charge. There's Marshall Brain's "Manna", of course, the dystopian version of this.
The Culture novels show a stable society that's run by intelligent machines yet is flexible, adaptable, can deal with crises, and is pleasant for humans to live in. They don't show how to get there. Which is a problem.
