Addendum: this is draft 2 of the space opera that, well, my elevator pitch was "Iain isn't writing any more, alas, so let's see if I can do something that makes readers feel the same way as his Culture novels without in any way being derivative of the Culture".
It's probably a failure on those terms, but I had to try, right?
@rooftopaxx No knife missiles whatsoever! Not even any AIs. There is some cute bioengineering, though. And a high concept: what is the universe going to look like in a post-science age (by which I mean, all achievable insights have long since been achieved, so there are no new breakthroughs, only stamp-collecting)?
At least the starships have notable names ...
