Consciousness - depending on your point of view - is either the mysterious thing that makes you human - or a quality you will one day share with artificial intelligence. David Deutsch is widely regarded as the father of quantum computing, and says consciousness is sort of like a piece of software, running on your brain. It's just a matter of figuring out the code. And giving the human body new ways to explore the world. What you gain - and what you might lose - when you're a cyborg.
