Regional perspectives
In Japan and South Korea, ideas of future robots have been mainly positive, and the start of the pro-robotic society there is thought to be possibly due to the famous 'Astro Boy'. Asian societies such as Japan, South Korea, and more recently, China, believe robots to be more equal to humans, having them care for old people, play with or teach children, or replace pets etc. The general view in Asian cultures is that the more robots advance, the better."This is the opening of an era in which human beings and robots can co-exist," says Japanese firm Mitsubishi about one of the many humanistic robots in Japan. South Korea aims to put a robot in every house there by 2015-2020 in order to help catch up technologically with Japan.
Western societies are more likely to be against, or even fear the development of robotics, through much media output in movies and literature that they will replace humans. Some believe that the West regards robots as a 'threat' to the future of humans, partly due to religious beliefs about the role of humans and society. Obviously, these boundaries are not clear, but there is a significant difference between the two cultural viewpoints.
Autonomy and ethical questions
As robots have become more advanced and sophisticated, experts and academics have increasingly explored the questions of what ethics might govern robots' behavior, and whether robots might be able to claim any kind of social, cultural, ethical or legal rights. One scientific team has said that it is possible that a robot brain will exist by 2019. Others predict robot intelligence breakthroughs by 2050. Recent advances have made robotic behavior more sophisticated.Vernor Vinge has suggested that a moment may come when computers and robots are smarter than humans. He calls this "the Singularity". He suggests that it may be somewhat or possibly very dangerous for humans. This is discussed by a philosophy called Singularitarianism.
In 2009, experts attended a conference hosted by the Association for the Advancement of Artificial Intelligence (AAAI) to discuss whether computers and robots might be able to acquire any autonomy, and how much these abilities might pose a threat or hazard. They noted that some robots have acquired various forms of semi-autonomy, including being able to find power sources on their own and being able to independently choose targets to attack with weapons. They also noted that some computer viruses can evade elimination and have achieved "cockroach intelligence." They noted that self-awareness as depicted in science-fiction is probably unlikely, but that there were other potential hazards and pitfalls. Various media sources and scientific groups have noted separate trends in differing areas which might together result in greater robotic functionalities and autonomy, and which pose some inherent concerns.
Military robots
Some experts and academics have questioned the use of robots for military combat, especially when such robots are given some degree of autonomous functions. There are also concerns about technology which might allow some armed robots to be controlled mainly by other robots. The US Navy has funded a report which indicates that as military robots become more complex, there should be greater attention to implications of their ability to make autonomous decisions. One researcher states that autonomous robots might be more humane, as they could make decisions more effectively. However, other experts question this.Some public concerns about autonomous robots have received media attention. One robot in particular, the EATR, has generated concerns over its fuel source as it can continually refuel itself using organic substances. Although the engine for the EATR is designed to run on biomass and vegetation specifically selected by its sensors which can find on battlefields or other local environments the project has stated that chicken fat can also be used.
