Sure, sci-fi is often very speculative, but lots also includes (for example) mystery elements, yet it would be strange to necessarily call all mystery stories set in a slightly future or alternate-contemporary timeline "sci-fi"

Surprisingly, nobody ever read Asimov for the positronic brains, either.
