An interesting read that attempts to convey the reason the P vs NP problem is important to those that do not have knowledge of complexity theory.
As a side note, one part that Lipton does not make completely clear, although with further reading should be obvious, is that his example umbrella statement Q is equivalent to the statement that P != NP.
