For over half a century, the silicon microchip has been the engine of human progress, the silent, microscopic heart of our modern world. Its relentless, predictable improvement, dictated by Moore's Law, has powered a revolution that transformed every aspect of our lives. But this golden age is ending. The laws of physics and economics are closing in, and the very foundation of our digital civilization is hitting a wall.

What comes next?

In "Beyond Microchip: Computing After Silicon," computer technologist Al Mahmud Al Mamun takes you on a breathtaking tour of the technologies that will define the next great epoch of computing. This is not a story of incremental improvements, but of a Cambrian explosion of new ideas—a fundamental reimagining of how we build machines that think.

From the laboratory to the philosophical frontier, this deeply researched yet accessible book is your guide to the coming transformation. Inside, you will discover:

The New Materials: An exploration of carbon-based computing with graphene and nanotubes, and the rise of powerful compound semiconductors like Gallium Nitride (GaN). Revolutionary Architectures: A deep dive into Neuromorphic Computers that mimic the human brain, Optical and Photonic Computers that operate at the speed of light, and the strange, powerful world of Spintronics. The Quantum Leap: A clear and accessible explanation of Quantum Computing, its potential to solve currently intractable problems, and the immense challenges in building these reality-bending machines. Living Computers: A fascinating look at the emerging field of DNA and Biological Computing, which harnesses the molecules of life itself for data storage and calculation. The AI Revolution Unleashed: An analysis of how these new forms of hardware will unlock unprecedented breakthroughs in Artificial Intelligence, leading to more efficient, autonomous, and creative systems. The Human Impact: A forward-looking look at how these technologies will reshape our economies, societies, and the very future of work, while examining the urgent ethical and philosophical questions they raise about consciousness, identity, and the nature of reality.

"Beyond Microchip" is more than a book about technology; it is a map to the next great age of human history. It is an essential toolkit for the engineers, scientists, business leaders, policymakers, students, and curious thinkers who want to understand and shape the profound changes on the horizon. The future is arriving faster than you think. This is your guide to understanding it.
