But it is quickly getting more and more complex, and, well, more intelligent.Stuart Russell teaches computer science at the University of California, Berkeley. He says humans should be sure to make AI products that we like.Russell sees artificial intelligence changing the economy and current ④ way of life. The health care industry is one area that artificial intelligence is already changing. AI can process⑤huge amounts⑥ of data, so doctors can use the most up－to－date⑦ information to diagnose⑧ and treat patients.There is also a dangerous side to artificial intelligence.
