Yeah, the article says that so far humanity's approach has just been "hope there isn't a black ball" and we know that hoping isn't a tactic; but the alternative (global collaboration and perfect adherence) seems impossible even in the ideal.
So, yeah. My personal tactic has been "live a good life while you can, pitching in where you can". Humanity really needs an "Arrival" scenario to get our shit together before a black ball annihilates us.
