Robotic surgery has been around since the late 1990s, but has been in use in the USA since 2000 and was used more in more than 350,000 surgeries in 2012 alone.The use of robotics (specifically the Da Vinci model currently being used and displayed in the picture) allows minimally invasive surgery: meaning far fewer incisions and no chance of items being lost inside of patients. The use of learning (or even sentient) computers, like those being worked on by Google, would make their use a more interesting question since current models require a human to control the robot. This in turn, means that any, of the few, errors coming from their use lies on the human side of the equation, so  always know your surgeon and possibly get a second opinion before surgery.
