Good call on those two XKCDs, but I think it's not society that believes that nothing exists outside what we can scientifically observe. Poets, writers and artists don't believe that. Hollywood makes a living out of not believing in that. Most people I meet don't believe that -- sometimes believing in all kinds of nonsense to an extreme I find irritating, but that's my problem :P

In any case, what's specifically irritating is the entrepreneur / startuper / tech bro belief that "we can make an app to solve this", which sometimes also occurs here on HN. No, not every problem can be solved with tech or an app. Even when it can, you Random Startuper are the sidekick of the story, not the main hero who's calling the shots.
