This is like the old saw "The best way to predict the future is to create it" or the inimitable Steve Jobs' version which goes something like "Users won't know what they want until I show it to them." Yes, I can tell you Jobs certainly was like that.
But the fact is that neither ground up creation of the future nor riding along and trying to predict the swerves is a complete strategy. You have to do both in just the right proportions.
Science fiction is the art of doing this on a fairly long time scale.
