Heartificial or artificial intelligence? How to program a friendly AI

Supercomputers are about to achieve a quantity and level of intelligence which allows them to grow hyper-exponentially over a short period of time. We call them superintelligences and this sudden growth poses some risks because they will be much smarter than the best human brains in practically every field, including scientific creativity, general wisdom and social skills (Nick Bostrom). I don't question that this will happen, as Ray Kurzweil said "Our intuition about the future is linear. But the reality of information technology is exponential, and that makes a profound difference. If I take 30 steps linearly, I get to 30. If I take 30 steps exponentially, I get to a billion.".
