When the LASER was invented in the 60's it was largely regarded as a "solution looking for a problem". Today we see LASER technology every day, in every walk of life, and the benefit to society is incalculable. Throughout history we've quipped "Necessity is the Mother of Invention"; and inventors occupied themselves solving problems and building better mousetraps. Today, as in the case of the LASER, "Invention has become the Mother of Necessity". Technological advancement pursued for it's own sake, only later to be repackaged into consumer products and marketed as the "Next Big Thing".
