Considering the random branches of science that have gone into making better hard drives, I'd be willing to put money on 'understanding dark energy' => 'higher density data storage' as one benefit of the tech.
But yeah, we understand more things, we're in a better position to understand even more things, and some have applications you benefit from every day.
The problem is that the volume of slop available completely overwhelms all efforts at quality control. Zealotry only goes so far at turning back the tsunami of shite.
