I’m just going to plus one for now. As ever you’ve given me food for thought.

I agree it’s an important distinction between science fiction and space opera (which is basically fantasy which happens to be in space, which is to recognise what it is rather than to knock it).

I also dislike lots of the cyberpunk assumptions. Why would someone graft tools onto their body, when external tools are easier to replace/upgrade and easier to service, as well as having the same functionality?
