NYTimes opinion writer David Brooks checks in today with one of his familiar big-picture think-abouts in column form. He’s being contrary today, blaming us collectively for a lack of imagination and daring. He claims we are in an innovation valley and that we better find some mountain climbers soon if we expect to get civilization moving in ways that will improve life on Earth. It’s his response of sorts to the loss of Steve Jobs. Read Brooks here, and get the NYT on your porch or online if you want more.
