Why is this even a surprise, people have been participating in AI challenges for long time (like these : http://ants.aichallenge.org/ ) and are well aware that those are hard problems, they develop heuristics since its not computationally possible to obtain perfect solution.

Side note: The results of research and insights derived thereof are worth sharing in their own right. It doesn't matter how obvious the result may be to a certain subset of people.
