Context paragraphs:
Open Letter on Artificial Intelligence: In January 2015, Stephen Hawking, Elon Musk, and dozens of artificial intelligence experts signed an open letter on artificial intelligence calling for research on the societal impacts of AI.  The letter affirmed that society can reap great potential benefits from artificial intelligence, but called for concrete research on how to prevent certain potential "pitfalls": artificial intelligence has the potential to eradicate disease and poverty, but researchers must not create something which cannot be controlled.  The four-paragraph letter, titled "Research Priorities for Robust and Beneficial Artificial Intelligence: An Open Letter", lays out detailed research priorities in an accompanying twelve-page document.

Aaron Sloman: Aaron Sloman is a philosopher and researcher on artificial intelligence and cognitive science who was born in Rhodesia (now Zimbabwe).  He is the author of several papers on philosophy, epistemology and artificial intelligence.  He held the Chair in Artificial Intelligence and Cognitive Science at the School of Computer Science at the University of Birmingham, and before that a chair with the same title at the University of Sussex.  He has collaborated with biologist Jackie Chappell on the evolution of intelligence.  Since retiring he is Honorary Professor of Artificial Intelligence and Cognitive Science at Birmingham.

Artificial intelligence in fiction: The literature of science fiction and fantasy is extensive and includes many subgenres which includes artificial intelligence as a recurrent theme in science fiction.  As a subgenre of science fiction, the fiction of artificial intelligence (AI) also applies the sub-themes of utopian and dystopian themes to its plots.  Artificial intelligence (AI) is a common topic of science fiction.  Science fiction sometimes emphasizes the dangers of artificial intelligence, and sometimes its positive potential.

System Shock 2: System Shock 2 is a first-person action role-playing survival horror video game for personal computers.  The title was designed by Ken Levine and co-developed by Irrational Games and Looking Glass Studios.  Originally intended to be a standalone title, its story was changed during production into a sequel to the 1994 PC game "System Shock".  The alterations were made when Electronic Arts—who owned the "System Shock" franchise rights—signed on as publisher.

Rollercoaster Mania: Rollercoaster Mania is a theme park game for Facebook.  It is developed by Noisy Duck and published by the 6waves.  It is currently the 22nd fastest-growing Facebook game by MAU with user figures up by 130,000 to 580,000 in a week which means a gain of 35%.  It is based on the 1994 PC game Theme Park on iOS developed by EA and so is likely to appeal to its fans.  It has almost exactly the same aesthetic, though its rearranged to focus on social play.

Artificial Intelligence: A Modern Approach: Artificial Intelligence: A Modern Approach (AIMA) is a university textbook on artificial intelligence, written by Stuart J. Russell and Peter Norvig.  It was first published in 1995 and the third edition of the book was released 11 December 2009.  It is used in over 1100 universities worldwide and has been called "the most popular artificial intelligence textbook in the world".  It is considered the standard text in the field of artificial intelligence.

SHODAN: SHODAN (Sentient Hyper-Optimized Data Access Network) is a fictional artificial intelligence and the main antagonist of the cyberpunk-horror themed action role-playing video games "System Shock" and "System Shock 2".

Weak AI: Weak artificial intelligence (weak AI), also known as narrow AI, is non-sentient artificial intelligence that is focused on one narrow task.  Weak AI is defined in contrast to either strong AI (a machine with consciousness, sentience and mind) or artificial general intelligence (a machine with the ability to apply intelligence to any problem, rather than just one specific problem).  All currently existing systems considered artificial intelligence of any sort are weak AI at most.

Nouvelle AI: Nouvelle artificial intelligence (AI) is an approach to artificial intelligence pioneered in the 1980s by Rodney Brooks, who was then part of MIT artificial intelligence laboratory.  Nouvelle AI differs from classical AI by aiming to produce robots with intelligence levels similar to insects.  Researchers believe that intelligence can emerge organically from simple behaviors as these intelligences interacted with the "real world," instead of using the constructed worlds which symbolic AIs typically needed to have programmed into them.

Friendly artificial intelligence: A friendly artificial intelligence (also friendly AI or FAI) is a hypothetical artificial general intelligence (AGI) that would have a positive rather than negative effect on humanity.  It is a part of the ethics of artificial intelligence and is closely related to machine ethics.  While machine ethics is concerned with how an artificially intelligent agent should behave, friendly artificial intelligence research is focused on how to practically bring about this behaviour and ensuring it is adequately constrained.
