The computer that decides if we live or die

Can the computer really decide if we live or die? This article is about this guy named Wendler who hopes to build up a broader data bank of personal profiles, which will include age, gender, religious and ethnic background, to advance the software. He is confident that will enable more accurate patient predictions. New software should soon be able to predict more accurately than loved ones how comatose patients would choose to be treated, if they were able to make the decision themselves. The study compared how accurately their computer-based tool predicted a patient's preferred treatments compared with what loved ones said. Results showed both methods got it right around two-thirds to three-quarters of the time. I think that it could help people but is it going to be more accurate than what we already have?
