How can we be sure AI will behave? Perhaps by watching it argue with itself.

Someday, it might be perfectly normal to watch an AI system fight with itself. The concept comes from researchers at OpenAI, a nonprofit founded by several Silicon Valley luminaries, including Y Combinator partner Sam Altman, LinkedIn chair Reid Hoffman, Facebook board member and Palantir founder Peter Thiel, and Tesla and SpaceX head Elon Musk. The OpenAI researchers have previously shown that AI systems that train themselves can sometimes develop unexpected and unwanted habits. For example, in a computer game, an agent may figure out how to "glitch" its way to a higher score. In some cases it may be possible for a person to supervise the training process.
