Gray on play

[C]reativity is a key to economic success. We no longer need people to follow directions in robot-like ways (we have robots for that), or to perform routine calculations (we have computers for that), or to answer already-answered questions (we have search engines for that). But we do need people who can ask and seek answers to new questions, solve new problems and anticipate obstacles before they arise. These all require the ability to think creatively. The creative mind is a playful mind.
