If Waymo has taught me anything, it’s that people will eventually accept robotic surgeons. It won’t happen overnight but once the data shows overwhelming superiority, it’ll be adopted.

[Our] policy is composed of a high-level language policy and a low-level policy for generating robot trajectories. The high-level policy outputs both a task instruction and a corrective instruction, along with a correction flag. Task instructions describe the primary objective to be executed, while corrective instructions provide fine-grained guidance for recovering from suboptimal states. Examples include "move the left gripper closer to me" or "move the right gripper away from me." The low-level policy takes as input only one of the two instructions, determined by the correction flag. When the flag is set to true, the system uses the corrective instruction; otherwise, it relies on the task instruction.
To support this training framework, we collect two types of demonstrations. The first consists of standard demonstrations captured during normal task execution. The second consists of corrective demonstrations, in which the data collector intentionally places the robot in failure states, such as missing a grasp or misaligning the grippers, and then demonstrates how to recover and complete the task successfully. These two types of data are organized into separate folders: one for regular demonstrations and another for recovery demonstrations. During training, the correction flag is set to false when using regular data and true when using recovery data, allowing the policy to learn context-appropriate behaviors based on the state of the system.
How does it handle problem cascades ? Like removing necrotic pancreatitis causing bleeding,c auterized bleeding causing internal mini strokes, strokes causing further rearranging emergency surgery to remove dead tissue? Surgery in critical systems is normally cut & dry, but occasionally becomes this avalancg of nightmares and add hoc decisions.
Complications happen in surgery, no matter how good you are. Who takes the blame when a patient has a bile leak or dies from a cholecystectomy? This brings up new legal questions that must be answered.

> "To move from operating on pig cadaver samples to live pigs and then, potentially, to humans, robots like SRT-H need training data that is extremely hard to come by. Intuitive Surgical is apparently OK with releasing the video feed data from the DaVinci robots, but the company does not release the kinematics data. And that’s data that Kim says is necessary for training the algorithms. “I know people at Intuitive Surgical headquarters, and I’ve been talking to them,” Kim says. “I’ve been begging them to give us the data. They did not agree.”
So they are building essentially a Surgery-ChatGPT ? Morals aside, how is this legal? Who wants to be operated on by a robot guessing based on training data? Has everyone in the GenAI-hype-bubble gone completely off the rails?
But what do you optimize for during training? Patient health sounds subjective and frankly boring. A better ground truth would be patient lifetime payments to the insurance company. That would indicate the patient is so happy with the surgery they want to come back for more! And let’s face it, ”one time surgeries” is just a rigid and dated way of looking at the business model of medicine. In the future, you need to think of surgery as a part of a greater whole, like a ”just barely staying alive tiered subscription plan”.
One potential problem, or at least a trust issue, with AI-driven surgeons is the lack of "skin in the game". Or no internal motivation, at least that we can comprehend and relate to.
If something goes off the charts during surgery, a human surgeon, unless a complete sociopath, has powerful intrinsic and extrinsic motivations to act creatively, take risks, and do whatever it takes to achieve the best possible outcome for the patient (and themselves).
