Unfortunately people still think very teleologically, as if nature works in a progressive fashion towards some structured end; this tendency is deep in western thought all the way back to Plato (and probably beyond), and it's all over science fiction.
That said, IMO there's a lot of things that could confound the usefulness of increased foresight. After a certain point (which humanity has likely passed) foresight is not a particularly visible measure of fitness except in those rare extinction events that require significant cooperation to survive. I suppose that even given that foresight is the most valuable trait for long-term survival of a species, it's very rare that it is selected for beyond a certain point because the events that it allows a species to survive are too rare to be selected against.
