A Layperson's View of Future Technology and Society    

Computers of Tomorrow

Today's computers operate using transistors, wires and electricity. Future computers might use atoms, fibers and light. Personally, I don't give a byte what makes it tick, as long as it does the job. If I could accidentally spill my coffee and not have it cost $848, that would be a cool feature.

But let us assume that you are not still bitter from a recent laptop replacement. You might stop to consider what the world might be like, if computers the size of molecules become a reality. These are the types of computers that could be everywhere, but never seen. Nano sized bio-computers that could target specific areas inside your body. Giant networks of computers, in your clothing, your house, your car.  Entrenched in almost every aspect of our lives and yet you may never give them a single thought.

Complete understanding of the theories behind these future computer technologies is not for the meek. For example, my research into quantum computers was made all the more difficult, after I learned that in light of her constant interference, it is theoretically possible my mother-in-law could be in two places at once.

If you have the heart, take a gander at this collection of articles and links on the most promising new computer technologies. If not, dare to imagine the ways that billions of tiny, powerful computers will change our society.

Moore's law

Visit any site on the web writing about the future of computers and you will most likely find mention of Moore's Law. Moore's Law is not a strictly adhered to mathematical formula, but a prediction made by Intel's founder co-founder Gordon Moore in 1965.

Moore predicted that computing technology would increase in value at the same time it would decrease in cost. More specifically, that innovations in technology would allow a doubling of the number of transistors in a given space every year, the speed of those transistors would increase and manufacturing costs would drop.

A computer transistor acts like a small electronic switch. Just like the light switch on your wall, a transistor has only two states, On or Off. A computer interprets this on/off state as a 1 or a 0. Put a whole bunch of these transistors together and you have a computer chip. Intel's newest processor has nearly 1 billion transistors.

Shrinking transistor size not only makes chips smaller, but faster. One benefit of packing transistors closer together is that the electronic pulses take less time to travel between transistors. This can increase the overall speed of the chip.

Not everyone agrees that Moore's Law has been accurate throughout the years, (the prediction has changed since its original version), or that it will hold true in the future. But does it really matter? The pace at which computers are doubling their smarts is happening fast enough for me.

Thanks to the innovation and drive of Gordon Moore and others like him, computers will continue to get smaller, faster and more affordable. 

IBM moves Moore's Law into the third-dimension

IBM announced a breakthrough chip-stacking technology in a manufacturing environment that paves the way for three-dimensional chips that will extend Moore's Law beyond its expected limits. The technology – called "through-silicon vias" -- allows different chip components to be packaged much closer together for faster, smaller, and lower-power systems.
