- people who only enjoy reading classic literature
- scientists and engineers who do not enjoy fiction
Explanation:
The Science Fiction is a very specific type of literature, and not everyone can connect with it, enjoy it, and be passionate about it. While some people see it as the best genre, and even dedicate their lives to it, some just see it something else that is not in their interest range, or maybe even their cognitive abilities. The people that are interested in classic literature would hardly be an audience of the Science Fiction as it is totally different from what they prefer. People who maybe have connections with it, and seem that would be interested, actually may have totally different interests personally. And unfortunately there are still people that do not know how to read. Those people are not interested in any type of literature, including the Science Fiction with the simple reason that they can no read it and understand it.
