Well Moore's Law is having one. The widely misquoted Moore's Law is forty years old. It all started with an article in Electronics Magazine. In that article Gordon Moore, co-founder of Intel, observed that the number of transistors in a microchip was likely to double in a short period of time. Since, with then existing designs, the number of transistors was directly related to the processing power of the micro this was quickly interpreted as computing power. Gordon came back in 1975 and clarified the prediction saying that the number of transistors would double every 24 months. Despite numerous reports of its demise, the rate of growth of processor power continues today. There are good reasons to believe that Moore's original prediction of the number of transistors on a micro doubling will eventually slow down because of physical limitations. However, there are many alternate approaches to increasing processor power that in research labs which will likely take over where the current approaches leave off. So happy birthday to Moore's Law and thanks for the laptops, pdas, cell phones, calculators, etc.
