Paul the octopus might have been the star of the 2010 World Cup with his accurate predictions, but Microsoft’s Cortana assistant is proving a worthy digital replacement for the now-deceased cephalopod. Microsoft started adding World Cup predictions to Cortana over the weekend, and she has successfully predicted four results, backing Brazil, Colombia, The Netherlands, and Costa Rica in their final 16 games. The new prediction functionality is part of regular updates that Microsoft makes to Cortana every two weeks, bringing simple improvements and new data to the service.
