content: Not really. Or to put it another way: it depends on how you define that "one thing". The AI doesn't "only predict lung cancer", the AI can collect vast amounts of information from different sources - more than any human ever could. It then uses this information to predict a likely outcome - something that humans try to but are very poor at doing even if you're an expert (as showed in the example in the article). To (roughly) quote a very well watched clip from youtube: "the future of AI is not brilliant programmers teaching super-smart AI's what to do, it is brilliant programmers building super-smart AI's that teach themselves what to do next". It is true however, as you say, that doctors are required for a lot of other things - but that's also the point of bringing AI's into the healthcare industry: doctors should do what they're good at, namely connecting with the patients, making operations etc. They should collect other information such as medical history, current life situation etc. and leave the hard data up to the AI.
