Computers play great chess, which is a game about predicting your opponent’s next move. It doesn’t require intelligence to play chess, since chess is a specialized form of computation.<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>Likewise, we can think of the weather predicting Kalman filter as a specialized form of computation, clearly a really cool one which results in the ability to predict weather very accurately but still not AI. I will stop whining about moving goal posts in the Kalman filter case.<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>spike<o:p></o:p></p></div></body></html>
