Lethal autonomous robotics: Coming to a theatre near you?

The use of drones (unmanned armed vehicles) by the United

States government against targets in northwest Pakistan along the Afghanistan border since 2004 has brought the technical, ethical and legal aspects of lethal autonomous robotics under the spotlight.  Prof Christof Heyns explains the difference between human judgement This was also the topic and technology-driven intelligence. under discussion at the The guest speaker, Prof Christof addition, one can achieve more with annual Hendrik van der Bijl Heyns, is pre-eminently qualifi ed fewer people, and one is able to to consider this subject, as United eliminate the weakest link (the human Memorial lecture, presented Nations Special Rapporteur on factor) and achieve results faster.

Prof Heyns concluded his presentation by weighing up the pros and cons of human judgement vs. computers. While human judgement has the advantage of experience, wisdom and qualitative evaluation, computers have the advantage of statistics, algorithms and quantitative evaluation. While human judgement has the benefi t of common sense, mercy and compassion, human beings also make mistakes, can be prejudiced, and may commit crimes. Computers, on the other hand are precise and fast, and have no fear of revenge. However, computers do not have the benefi t of common sense and compassion.
