Nothing right at all? From the wiki entry:

> In 2015, a calibration of the updated World3-03 model using historical data from 1995 to 2012 to better understand the dynamics of today's economic and resource system was undertaken. The results showed that human society has invested more to abate persistent pollution, increase food productivity and have a more productive service sector however the broad trends within Limits to Growth still held true.

Which makes it a curve fitting exercise. They didn't match anything - they changed all the parameters to match the historical dataset, and then declared that now the future prediction is correct.

Give it 20 more years, they can "recalibrate" again and find another imminent collapse: any model with enough free parameters can match any input you like.

Unless I’m misreading the wiki, the deadline of the collapse didn’t change to 20 years further out. The data seem to continue to match the original prediction.
