The fact that the brain exists says absolutely nothing about the future of chip manufacturing. It is on a completely different plane than Moore's law: neurons are only as small as .004mm at minimum. What you're suggesting isn't an improvement, it's starting over completely from scratch.

But just to humor you, today's best processors have a transistor density of roughly 25M transistors per mm^2. The human brain has a neuron density of 14K neurons per mm^3. And of course, the human brain has a volume 250x the average desktop processor.
