I cannot tell why the spokesmen I have cited want the developments I forecast to become true. Some of them have told me that they work on them for the morally bankrupt reason that "If we don't do it, someone else will." They fear that evil people will develop superintelligent machines and use them to oppress mankind, and that the only defense against these enemy machines will be superintelligent machines controlled by us, that is, by well-intentioned people. Others reveal that they have abdicated their autonomy by appealing to the "principle" of technological inevitability. But, finally, all I can say with assurance is that these people are not stupid. All the rest is mystery.
