I mentioned this elsewhere in the thread, so at the risk of repeating myself, how does The Martian not qualify as Sci-Fi, hard Sci-Fi at that? Sure the majority of the tech exists today but not all of it (habs, the ships themselves, etc) and certainly not all of the tech has actually been built or tested.

So it's set in the future, it's about scientists and science, it's about a big idea (even more so when it was written) - sending human's to Mars, and it's fiction. Honestly I don't understand how that can't be Sci-Fi through and through. Is it because the tech isn't vastly advanced over what we have now? Because 30 years ago smart phones were Sci-Fi, in 1870 submarines were Sci-Fi, in 1634 the moon and it's relationship with the Earth (Kepler's Somnium) was Sci-Fi. If those qualify I'm not sure how The Martian fails to.

Again not offended at this, just really curious how people draw that conclusion.
