the way computers work at the moment, is by passing an electric charge between two different points, in a binary I/O gateway. however, with chip capacity doubling every 18mths or so by refining the manufacturing process to get twice as many connections into the same space, we're rapidly approaching the point were the distance of the gap will be smaller than the diameter of an electron, so something new, and more exotic, had better be on the horizon, or the computer industry is going to come griding to a halt!
As far as I'm aware, the exponential growth of switches on a processor is expected to start slowing more rapidly (Moore's law used to be every year). There just isn't enough room anymore, as you state. I mean there had to be a limit.
If you look at the Wiki page for quantum computing you'll see that there have been a few cases over the past years where researchers, including IBM, have stated that they have almost demonstrated working quantum computers.
If and when that day comes it's goodnight to the world as we know it. Goodnight to online privacy. Today's standard encryptions Will be obsolete and easy to penetrate. Very few understand (and I include myself in this) just how powerful a quantum computer Will be.
'People are just not informed about this country's [Britain's] real role in the world. They are provided with systematically distorted views and information about the past and present that makes it easier for elites to pursue their policies in their interest and often against the public interest.' - Mark Curtis, page 356, 'Web of Deceit'.
