Siri is fun to play with - ask her what the meaning of life is sometime - but I am still not sure she offers real, usable information that a quick internet search wouldn't give me, and I wouldn't have to repeat three times. However, people like Tim Berners-Lee dream of a time when you could ask inocuious questions like where to take your spouse for dinner and receive a response based on natural language processing and what I call insight. Insight into the food preferences of both you and your spouse, restaurants nearby and their table availability. The latter two are not as difficult, but insight would be an achievement that most men would like to possess on their own.
