Science Fiction

1.) You ought to mention "Stranger in a Strange Land" -- Heinlein, it suffers from all of his flaws, esp. fatuous female characters, but is certainly competitive with "Mote in God's Eye" in terms of influence, of breaking new ground. "Can you grok it?" One of the first to break into the mainstream.

2.) It was all pulp to start with, so it's mostly "pulpy", and this is still true, I'm reading through Kim Stanley Robinson now, who is definitely "modern", and I am jarred all the time by the product placements and little commercial bits littered about, and other things too, but you are going to see that with any author who is doing mass-market work.

3.) Everything changed in the 60s, and it has kept right on changing. Prior to that, what we call right wing was just about all there was.

4.) But yeah, I agree, Ayn Rand in Space, a lot of it.
