Today's silicon-based computers are limited in their speed by the speed with which they can transfer data and the speed with which that data can be processed via logic gates. That being the case, it stands to reason that a primary factor limiting the speed of current computers is the speed with which electrons move around inside the silicon chips, which is roughly half the speed of light in a vacuum.1
David Levy says that computing technology of the future will be impossible without a change in the way computers are made (materials, size, etc.)2
New conducting materials developed at NASA's Marshall Space Flight Center can act as computer logic gates that perform 1,000 times faster than today's fastest silicon chips, and are smaller. And researchers at the University of Rochester believe that their work could lead to a computer more than a billion times faster than the fastest supercomputer was at the beginning of the 21st century. Now that, friends and neighbors, is fast
Leonard Adelman, who coauthored the RSA encryption algorithm, introduced the idea of using DNA to solve complex mathematical problems. And in 1997, researchers at the University of Rochester actually developed DNA logic gates. I won't even get into a discussion of quantum computing.
Here's my question: I want to know how powerful (memory capacity, processing speed) you guys think that PCs will be in 2050, and in 3000 A.D. And, secondly, what everyday applications will such powerful computers, using A.I., be put to in those two years, respectively?
1. I.e., electron speed in our CPUs is approximately 93,000 miles per second.
