Imagination, Human and Artificial

Humans imagine things. We live our lives in great measure by imagining circumstances a bit different from what we find, and then (again using imagination) we explore what it might take to bring those circumstances about, or what it might be like to live in such circumstances. We do this regarding issues large and small, all day long, every day. It is how we operate, and it gives us a huge leg up in detecting and repairing our own confusion as we negotiate this complex dynamic world. It is also quite different from how our artificial systems operate.
