Evolution of the Idea

I never realized how ubiquitous the symbolism for an “idea moment” was until I considered its use in a historical context. The pre-twentieth century “ideas” don’t quite depict that flash moment of brilliance that we associate with turning on a light. Using the traditional incandescent bulb in today’s green-conscious world seems too anachronistic. Will adopting a revised symbol of the light bulb be necessary as advances in technology render the original unrecognizable? Add this to your list of things to lose sleep over.
