Federico Faggin is one of the greatest luminaries in high technology today. As a physicist and inventor of the microprocessor and MOS silicon gate technology, he has contributed to the infrastructure of modern computing. With his proven knowledge and experience, he now turns his attention to consciousness and the nature of reality, sharing with us his profound insights into classical and quantum worlds, artificial intelligence, life, and the human mind. In this book, he analyzes an idealistic model of reality, which emerges after years of thought and direct experience, according to which the most fundamental level of nature is that of consciousness as a quantum phenomenon, while the classical physical world is merely a symbolic representation of a deeper reality.
