I kind of thought that cyberpunk tended to explain a lot less than more traditional SF intentionally. You get thrown into the chaos, the same as the characters are thrown in. As compared to traditional SF, which often pauses at the beginning as a professor explains the situation to someone. The lack of that break also speeds up the action.

I think it's far easier than Dune, though.

Neither are hard SF, if you are referring to hard SF, meaning accurate scientifically.
