There is a controversy whether an AI can have an ethical mind. Some researchers are warning that robots with an AI would become a serial killer.
Although I do not support this idea entirely, we should be aware of the risk of creating a mass killing machine with an AI. Most people hesitate to take a trigger against a living person in front of you even if he is an arch enemy of you. But an AI is free from emotion. If you input the condition of shooting the gun, the robot will adhere the rule.
Thus, a robot can be an excellent war machine, as if in the film of Ironman. And there are some academic facilities are engaged in the development of the new weapons.
Recently, Korea Advanced Institute of Science and Technology (KAIST) was harshly criticized by abroad researchers. They believed that KAIST was committing to develop AI weapons collaborating with Hanwha Systems.
Toby Walsh, a Professor of Artificial Intelligence at the University of New South Wales in Sydney called for a boycott of the KAIST's project to AI researchers. His statement was supported by a total of 50 researchers.
The leader of KAIST commented that it had no intention to create the human-killing machines. This reply seemed to have satisfied the active researchers. Now, the boycott has been canceled.

I believe the possibility that AI technology will bring us a happier life. But, all useful tools have a dark side. Knives, cars, and the internet can be used in the war. We should continue to observe the development of AI industry.
