At the heart of my theory is a simple but powerful insight: the human brain operates as a hierarchy of pattern recognizers. Each layer of the neocortex receives inputs, detects regularities, and forms representations. These representations, in turn, become inputs for higher layers that recognize mor...

The neocortex is a thin sheet of tissue, folded multiple times to fit within the skull, but its apparent simplicity hides an extraordinary uniformity of design. Each cubic millimeter contains about a hundred thousand neurons arranged in similar vertical structures, known as cortical columns. Every c...

To appreciate where we are going, we must first understand where we have been. Throughout history, each major technological epoch has built upon the previous one, compressing centuries of development into ever-shorter spans. The mechanical computers of the early twentieth century—the gears and relay...

From The Age of Spiritual Machines: When Computers Exceed Human Intelligence

At the heart of my argument is a principle that governs all technological progress: the Law of Accelerating Returns. Unlike linear growth, which moves at a steady rate, exponential growth multiplies upon itself. Moore’s Law—the observation that computing power doubles roughly every two years—is just...

From The Age of Spiritual Machines: When Computers Exceed Human Intelligence

For decades, economic models and scientific projections assumed that progress moved linearly—slow, steady, predictable. Yet the evidence tells a different story. I illustrate how every major advance in computation, from the vacuum tube to the integrated circuit, follows an exponential curve. Each ge...

From The Singularity Is Near: When Humans Transcend Biology

The story of acceleration reaches back through history. I draw parallels between the evolution of life and the development of technology: DNA as the first information processor, neurons as a biological computer network, and civilization as a vast data transformation system. I examine data series fro...
