Microsoft’s Cortana digital assistant has successfully predicted eight World Cup results with 100 percent accuracy so far, but just as the games are getting more difficult to pick, she has fresh competition from Apples Siri. While Microsoft added its World Cup predictions to Cortana last weekend, Siri didn’t appear to offer its own estimates on the games in our own testing until later this week. If you now ask Siri variations of who will win a particular game, she offers up some noncommittal responses. It’s a tossup (if you’ve got a coin, heads says France win, tails says Germany), is Siri’s France vs. Germany prediction, while I don’t have the line on this one, but Colombia has a better record than Brazil is the estimate for today’s other game.
