Human-level AI is a giant risk. Why are we entrusting its development to tech CEOs?

Technology companies are racing to develop human-level artificial intelligence, whose development poses one of the greatest risks to humanity. Last week, John Carmack, a software engineer and video game developer, announced that he has raised 20 million dollars to start Keen Technologies, a company devoted to building fully human-level AI. He is not the only one. There are currently 72 projects around the world focused on developing a human-level AI, also known as an AGI -- meaning an AI which can do any cognitive task at least as well as humans can. Many have raised concerns about the effects that even today's use of artificial intelligence, which is far from human-level, already has on our society.
