THough, the current s curve is in processors. We are still at the
beginnning of the cost/performance curve with respect to
multiprocessor/neural net computers. I think once we start to hit the
wall with processors, we'll start to see more and more affordable
multiprocessor PCs, which ought to last another decade at most before
another wall is hit, at which point more exotic technologies will start
to become available, as soon as the neural computers are cheap enough to
make widespread use in engineering applications. This will bootstrap the
affordability of the R&D to develop the new exotic technologies.

To those who live it, they will never notice any drastic change, and no
singularity, per se, will be reached. People will always consider the
limit of the knowable to be x many development cycles in the future.
Granted, as things speed up and people get smarter and smarter, x will
continually shrink, but the amount of shrink will diminish over time to
a set amount of time in which extrapolation is reliable. Remember, an
event horizon is only such in relation to a specific point in the past,
it itself has no fixed point.
