Which means they will miss the real top performers. The savants who are capable of flashes of brilliance that can make whole new industries. These people will most definitely fall outside any measure / quantifiable scale that any company uses for comfort.
They apparently want people are having flashes of brilliance at this moment. They don't want them on their payroll once the flash dies. Then they want the next set of savants in form.
Its basically the equivalent reducing the great people to Kleenex. Once used, they want to throw them. Then buy the next Kleenex box.
