BartlebyScrivener writes "An article in The Economist examines Moore's Law as applied to razor blade technology: 'For the most cynical shavers, this evolution is mere marketing. Twin blades seemed plausible. Three were a bit unlikely. Four, ridiculous. And five seems beyond the pale. Few people, though, seem willing to bet that Gillette's five-bladed Fusion is the end of the road for razor-blade escalation. More blades may seem impossible for the moment — though strictly speaking the Fusion has six, because it has a single blade on its flip-side for tricky areas — but anyone of a gambling persuasion might want to examine the relationship between how many blades a razor has, and the date each new design was introduced'" I'm legally obligated to mention the Onion article that predicted this.
