Artificial Intelligence

**Artificial Intelligence** (人工知能, *Jinkō Chinō*?) (**AI** for short) refers to intelligence devised for and demonstrated by machinery and electronic systems as opposed to humans and other life-forms. The term is used both for the capability within systems and for individual entities.

AI is present throughout the world of science, both outside and inside Academy City, to a higher degree in the latter with greater levels of automation and higher general capabilities.

## Principles

The capabilities of an AI depend on its level of development and the processes that went into it, as well as the intended functions it was designed to perform. Some may be fairly simplistic and others may have a high level of information processing capability, though not have intelligence in the same way as a sentient human being. A long-held goal in the field and a long-envisioned idea in science fiction is the development of AI with the same level of independent thinking capability as a human being or higher, but very few AIs in the series have been shown to have reached that level.

Some AIs are meant to operate devices autonomously, while others support human operators in doing so. In the development of AIs, the 'thinking' and 'creative' processes might be designed and refined during the pre-release development process, while others are taught over time after implementation - sometimes through the inputs of its users.

AI is utilized on and can be found on a variety of devices besides computers, portable electronic devices, and their associated systems, networks and servers, particularly inside Academy City. Their usage extends from household appliances such as washing machines and ovens, to autonomous robots and self-driving vehicles, to Powered Suits and military weapons (such as Academy City's HsPS-15 and HsAFH-11) - with Academy City's heavily automated military making extensive use of AI technology.

Some AIs are built onto a system and cannot be easily moved, while other programs can be transferred between and downloaded onto devices. Examples of the latter include American IT company Grapple's commercially distributed virtual assistant Seri, and Aneri, distributed in Academy City and a downgraded version of Reading Thoth 78, which is an example of the former - a parallel processing device built into the Windowless Building.

There are a number of rumors and urban legends in Academy City connected to AI, including a false rumor of the dark side intermediary Spider Queen being an AI with no real form, as well as rumors that Imaginary Technology's AI secretly controls the Board of Directors from behind the scenes, along with the world's ethics, militaries and economies via the internet. There are also anti-AI groups, such as one that attempted to destroy an unmanned helicopter during a previous Daihaseisai.

During the Daihaseisai, most ordinary traffic was prohibited and much of the festival's transportation involved the widespread use of automated buses in restricted conditions, despite the difficulty of using them.
