A robot trained on videos of surgeries performed a lengthy phase of a gallbladder removal without human help. The robot operated for the first time on a lifelike patient, and during the operation, responded to and learned from voice commands from the team—like a novice surgeon working with a mentor.
The robot performed unflappably across trials and with the expertise of a skilled human surgeon, even during unexpected scenarios typical in real life medical emergencies.
Have you considered that the machine is made by a collection of humans?
Yes. But if the machine has proven to work reliably it will usually do so for its lifetime, while humans are prone to e multitude of errors. Especially in the medical field.
