It will be because people will be scared out of their minds of artificial intelligence. Artificial intelligence will be the scariest thing imaginable in the 21st century. With the current rates of change in technology, the supercession of mankind by some aglomeration of intelligent entities seems inevitable. Human beings will always be in control of their creations. We can make it that way.
Programmers can limit their creations to what they find sufficient.
There is no need to phase out the greatest species ever to evolve on this planet. We can hire people to think like people. What is useful is a machine that can solve problems and learn. We don't need one that decides it's having a bad hair day. We need one that can see how a nut and bolt go together and figure out that it works for all nuts and bolts.
