Thanks for posting this, Brian. I'm in two minds, really.
I’ve never believed that the only SF is hard SF, and that any sort of deep characterisation is a betrayal of the genre. And, naturally, almost every modern writer wants some sort of reader engagement with characters to keep them wanting to read on. On the other hand, I’m uncomfortable in trying to force the reader’s experience of the book into a template.
Perhaps it's genre snobbery, but I don’t like the idea of a literature of ideas moving towards a literature of "the feels". I suspect that a lot of people who started reading before the internet are the same. Even in books like, say, Tinker Tailor Soldier Spy, when there is danger and intrigue and you don't want the (comparatively) good guys to be injured, the primary enjoyment for me doesn't come from emotions but from wanting to find out what happens next. It's a sense of being engrossed rather than emotionally engaged. Certainly there are moments where the question becomes "How will they survive?" but for me, the main reason for reading on is to learn what happens next and discover more about the setting.
