In 1974, a few months after the 8080 hit the market, Faggin left Intel and started Zilog, where he conceived the Z80 microprocessor.
"The Z80 is one of the most successful microprocessors ever produced," he said. "It is still in high-volume production today, more than two decades after it debuted."
Before retiring a few years ago, he founded and was CEO of three start-up companies. At one of his start-ups, Synaptics, he helped bring the human touch as a way to interact with computers. Synaptics produces human-to-computer interface products using neural networks and mixed-signal technology, and is best known for capacitive sensing touchscreens and the TouchPad, which is used on many laptops today.
Retirement has allowed him to return to his passion for science, philosophy and design, and exploring the role of technology in our lives.
"Since I retired from business a couple years ago, I have started a non-profit foundation for the study of consciousness," said Faggin. "Consciousness, in my way of looking at it, is the new frontier. It is what defines a human being, and distinguishes it from a machine.
"They [computers] will allow human beings to recognize what makes them human and people will recognize how much more powerful a human being is than a machine."
He believes that quantum computers could fundamentally change the nature of computing beyond the capabilities of today's mechanical computer.
"As for whether computers that are quantum or not can rival human intelligence, I have my doubts," said Faggin.
Does Faggin believe that computers can replicate human intelligence or consciousness?
Yes. I would.
