There is one brain organ that is optimised for understanding and articulating logical processes and that is the outer layer of the brain, called the cerebral cortex. Unlike the rest of the brain, this relatively recent evolutionary development is rather flat, only about 0.32 cm (0.12 in) thick and includes a mere 6 million neurons. This elaborately folded organ provides us with what little competence we do possess for understanding what we do and who we do it.

Mobile phones are misnamed. They should be called gateways to human knowledge.

By the time we get to the 2040s, we'll be able to multiply human intelligence a billionfold. That will be a profound change that's singular in nature. Computers are going to keep getting smaller and smaller. Ultimately, they will go inside our bodies and brains and make us healthier, make us smarter.

A lot of movies about artificial intelligence envision that AIs will be very intelligent but missing some key emotional qualities of humans and therefore turn out to be very dangerous.

We'll be able to have very intelligent, little robots with computers going inside our bloodstream, keeping us healthy from inside, destroying cancer at the level of one cell.

Death is a great tragedy…a profound loss…I don’t accept it…I think people are kidding themselves when they say they are comfortable with death.

What we spend our time on is probably the most important decision we make.
