Robot surgeon cuts health costs?

A robotic surgical machine just completed the world's first unassisted heart surgery. There were surgeons standing by in case something went wrong, but nothing did. The machine was programmed with the data from more than 10,000 similar operations. It's an interesting concept, and could have the potential to change the way health care is delivered in poor areas of the world, where doctors are few.

If the choice is between dying from a life-threatening illness because of a lack of human surgeons, or going under a robotic knife, my guess is that most people will choose the latter.
