It seems that the Moore law for silicon computers is almost dying these days. Computer chips (brains) won't be able to be much smaller or much faster due to physical limits. But is that the end of computing evolution ? I don't think so. Actually the computing power should not be measured by the physical brain, but the number of data it can handle in a given time (that's what benchmarks do). And actually you could have 1000 current CPUs computing 1000 more data the current CPUs. All we need is only faster memory, and especially memory bandwidth. That's why 64 bits computing is getting so important now as another way to keep on having more 'brain' power... I think that's what I'll keep in mind when I buy my next computer.
