For those who have been on the internet a while, they’ve probably heard of Moore’s Law. Unfortunately, this law often gets misquoted or misunderstood, but few people ever question the status of this law. Saying that computing power doubles every two years is the simplest way to quote Moore’s Law.
Why People Like This Law
Most people fall in love with laws that predict the future of a big industry. It should, however, be understood that the physical basis of the law means that it will differ slightly, and at the same time, it won’t be as reliable either. Gordon E. Moore first proposed the Moore’s Law in a magazine by Intel, even though he never gave it that name.
What Does Moore’s Law Say?
The meaning of Moore’s Law looks more technical than what a person might first believe. This law says that the number of transistors put into a unit will double every two years. Experts have found this law to be impressively accurate. In fact, the pocket-sized smartphones of Crysis 3 with the ongoing computerization of the economy has proven it true.
Moore’s Law Not Always True
Even despite the relative accuracy of this law, people should remain cautious of saying it will always be true. People must remember how when Moore first made this law, he had an original prediction of it doubling every year, but he eventually changed it to every two years. With some of manufacturing’s physical limitations on these chips, the number could even be brought back to five years or more. This would forever render Moore’s Law as invalid. While his prediction has usually proven true, that might not always be the case in the future.
Today’s world manufactures all the processors from silicon. After oxygen, silicon is the second most common element on earth. Despite its widespread availability, silicon has its limits as a conductor and the mobility of its electrons have a hard limit on how much you can densely pack the silicon resistors. Power consumption becomes a big issue as well because of an effect that is known as quantum tunneling. This is where keeping the electrons contained beyond a thickness threshold could have an impact. To keep Moore’s Law over a longer period of time, technology companies will need to come up with better materials for the next generation of computers.
