In the tech industry, barely a week goes by without one entity saying that another one is doomed. Mostly, however, we just ignore them, but when Princeton claimed that Facebook would collapse in 2017, the social network decided to get its own back.

Then the team went one step further, analyzing Google trends and Facebook likes to learn that, if social engagement stats are to be believed, the planet will run out of air at some point in 2060.
