Computer Speed

Speed

Most people tech-nerds know of Moore’s Law from 1965 (the number of transistors we are able to cheaply put in computer chips doubles every year, thereby doubling the speed).  However, most people don’t know that Moore, himself, came out and said his law will most likely fail finally in 2020 where the number of transistors we can put on chips will be limited by the laws of physics. Does this mean the exponential rise in computer processing speed will come to a halt in ten years?
Not a chance, says Jim Tully, chief of research for semi-conductors at Gartner. “The technology which will replace this is a bottom-up approach, where chips will be assembled using individual atoms or molecules, a type of nanotechnology.”
Ray Kurzweil, a well-respected Futurist, stated in 2008 that when this molecular computing technology comes out in 2020, computers will have the intellectual capability of human beings. You might want to digest that for a minute before moving onto the next section.

Size and Usability

That Macbook Air is pretty damn thin. So thin, in fact, that it makes you wonder if physical computers will even exist in 2020. Well according to developers at Intel, the keyboard and mouse surely won’t. Who needs QWERTY when you can control a computer with your mind?
“We’re trying to prove you can do interesting things with brain waves,” said Intel researcher Dean Pomerleau. “Eventually people may be willing to be more committed … to brain implants. Imagine being able to surf the Web with the power of your thoughts.”
Pomerleau and countless research groups around the world are working with brain scanning devices to map blood flow in the brain. They have found that when different individual focus on the same image, they have very similar patterns of blood flow in their brains. For example, one British group announced that they could discern where subjects where in a computer generated virtual environment by looking at where blood flowed in their brains.
