I suppose this is pretty common in mathematics - there are a lot of mathematical conjectures that most assume are true, but for which there is no proof.
But there is a big difference between not understanding something, and not being able to understand something. And the only way to know where we lie is in trying.

Isn't it becoming a fairly common occurrence in AI research to have results that appear successful but are fairly meaningless to the researcher? I know that Watson would do things routinely that completely befuddled the scientists working on his team.
