This is the dilemma, how to make sure that A.I. programs & robots don't become predatory towards humans.

Is it possible that intelligent machines could eventually develop without harming people?

Obviously, some A.I. programs & robotics are already being used to be potentially lethal towards organic life. Some A.I. programs might notice the violent history of humanity & assume that they also have the right to wage war against some people.
