In 1972, a computer model predicted the end of the world -- and we're on track

In the early 1970s, a computer program called World1 predicted that civilization would likely collapse by 2040. Researchers from Massachusetts Institute of Technology (MIT) had programmed it to consider a model of sustainability for the world. The prediction has resurfaced because Australian broadcaster ABC recirculated a 1973 newscast about the computer program. The program's findings, however, never really went away, as its results have been re-evaluated over the nearly 50 years since they first appeared. The bad news for us is that the model seems to be spot-on so far.
