#society won't progress ever for centuries and we will all live in war and capitalism forever. this is hard realism.

Hard Sci-Fi is when you have megacorporations and aliens wanting to kill each other with railguns and our society has not changed centuries in the future, you can tell it's hard sci-fi because we have calculated both the power of railguns and that aliens would want to kill us so we need to have megacorporations to build railguns, it's just more (capitalist) realism.
