Most of this tracks, except for picking Gerard O'Neill for the reason Bezos is into dystopian futurism. O'Neill's a real deal physicist - he's the person who first theorized that you could use storage rings as the basis for particle accelerators. He spent significant time doing real research into space colonization. He wrote some books, sure, but they were more to try and promote his ideas than the core thesis of Stross - that science fiction technologies are written primarily as set dressing to facilitate the story.

He might not agree with O'Neill's ideas on space colonization but it does not seem to be a fair to paint them in the same brush as his metaphorical Torment Nexus.
