Sci-Fi is about understanding the unknown and searching for meaning.
If you want to see what undilluted, pure science fiction is, without an adventure/action/drama/whatever coating, read "His Master's Voice" by Stanislav Lem. It's about a bunch of scientists being gathered to try and figure out what a repeating pattern in the universe's white noise means, and if it means anything at all.>>88879895
That kind of fits, and I guess you could use "Techno Fantasy" for Cyberpunk/Steampunk looking stories that don't actually fit those genres narratively.
Still, Fantasy itself kind of implies that the story has something to say about the fantastical world being built, which STD probably fits, but there are examples of the contrary too.
Just in general I don't like the idea of a setting style being interchangeable with a genre, which is supposed to be what the story is about.
