Hah, well then, maybe I just don't like vampires!

In all seriousness, I thought I had seen it in a list of "top hard sci-fi books" awhile back and a quick Kagi search seems to imply that a lot of people seem consider it hard sci-fi for whatever reason.

Maybe this means there's still a chance for me.

Somebody will always say something like this on any thread anywhere on the internet about any sci-fi. I dont know whats so attractive about gatekeeping "hard scifi" but it must be satisfying since so many people feel compelled to do so.

Regardless Blindsight is a good book and definitely has interesting concepts and good writing throughout.
