Artificial intelligence is only getting more powerful. Today, we're able to build computer programs that can master complex strategy games and even hold natural-feeling conversations. A new study on a specialized AI algorithm found that it was able to automatically diagnose a disease that causes childhood blindness more accurately than trained physicians can, a step towards automating medical tasks that are often bottle-necked by a shortage of doctors. The algorithm was developed and studied by scientists at Oregon Health and Science University and Massachusetts General Hospital. It was trained to diagnose a disease called retinopathy of prematurity (ROP) that, if untreated, will lead to total blindness.
