The dangers are very profound. You have talked about the intertwined promise and peril of this century in the context of technological change. If you look at today, you can see tremendous benefit from technology by looking back 200 years when human life expectancy was half what it is today. We're measurably better off, but there are also many dangers. We have the firepower to blow life off the planet, and there are lots of other weapons of mass destruction.
Technology is powerful and gives great power to individuals.
It's very democratizing but also enables destructive elements. We're talking about the duality of human nature, and it can be very creative or also very destructive. That's exactly what machines will achieve when we emulate human intelligence. My sense of that is the year 2030. We will have a fully reverse-engineered human brain and understand how intelligence works.
