Various scientific fields over the course of history have hoped to master Nature for the benefit of humankind. At the top of the heap right now is artificial intelligence (AI), which has allied itself with the technology of robotics. Between them AI and robotics are having a sizable impact on the work force as more and more jobs get automated. Advocates of AI are both supremely optimistic and nervous. Both relate to the possibility of a super-intelligent machine that would far surpass human intelligence.
If you are an optimist, this so-called Singularity, as the hypothetical machine is called, would become self-improving. Its software would become free of human constraints, and in a “runaway reaction,” it would keep improving its knowledge and the technology that knowledge creates. The result would be a revolution in human civilization—or its demise. The worriers are nervous that the Singularity could initiate global war on its own, or perhaps turn on us as its inferior and deal us some other kind of fatal blow, for the good of life on Earth.
