"Despite the potential benefits, experts are worried about what could go wrong with A.I.
For one, such a level of automation could take people’s jobs. This concern has emerged with automated technology before. But there is a difference between a machine that can help put together car parts and a robot that can think better than humans. If A.I. reaches the heights that some researchers hope, it will be able to do almost anything people can, but better.
Some experts point to existential risks. One survey asked machine-learning researchers about the potential effects of A.I. Nearly half said there was a 10 percent or greater chance that the outcome would be “extremely bad (e.g., human extinction).” These are people saying that their life’s work could destroy humanity."
