Do you really need to read entire sci-fi novels to extract whatever cool ideas they may have? In terms of getting ideas for startups, 99% of a novel is probably irrelevant and it might be better to have a resource that just gives you the 1% that matters.
Any given idea in sci-fi (are they going to make us refer to it as syfy now?) may or may not be particularly useful in and of itself. Most ideas is sci-fi are completely impractical anyway, so why fret about it?
Art / literature / music / what have you are not resources that can be mined. You can't freebase Heinlein (though I like the thought) or take a bump of Ernst.
Follow your interests, experience works as a whole, and don't expect to be changed.
I would argue that the difference between sci-fi and pop business is that few people truly enjoy business books (not to mention the fact that most business books have a shelf-life of 12 minutes.)
They read them because they believe that they will put them on the path to, well, I don't know what. True there's wisdom to be had out there, but, you usually can't buy it for $19.99+S/H, regardless of genre.
You can read "Time Enough For Love" or just the "Notebooks of Lazarus Long."
You can drink wine with your friends or dash your brains out with 190-proof Everclear.
