Actually, AI already saves lives. In several countries, mammograms are examined by AI and radiologists. Reliability is improved. In the EU, every car sold must be equipped with Automatic Emergency Braking Systems. That's AI. They reduce frontal collisions by 40%. Modern MRI machines are equipped with AI technology that reduces the time of imaging by 4x or more. You can now get a full-body MRI in 40 minutes for about $1000. Reduced time -> reduced cost -> more/earlier detection. And that's not counting the progress in medicine enabled by modern AI, including Nobel Prize-winning protein structure prediction.
