This is impressive. The precision and accuracy are far more significant than a human surgeon. Humans can work at an organ level. Robotics can work at a cellular level.

Here's a video explaining NeuroArm and some of the challenges building a robot that can work within an MRI machine.
With improvements in robotic surgery, proton therapy, vaccines and the next generation of smart chemotherapies, I'm guessing that by 2050, all but the most aggressive and late stage detected cancers should be fully treatable. If early detection screening is mass deployed by then virtually nobody with access to the technology would be dying of cancer.
