They can see patterns in what they do, but you have to tell it what to look for in patterns, then what to do with it.
If I had a microphone input, my form1 wouldn't start doing text to speech unless i told it i was speaking, and these words represent strings or actions, which we pickup as children.
And as children, we can't be told that they are actions, we learn. The day microsoft releases an application that can learn without being told what to learn, is the day computers learn.
Then again, Scoble seems to learn... odd..
