Jfc no one is learning surgery from a video. A resident looks up an article or a textbook chapter, watches a video, then assists - and when they’re assisting, they’re better prepared because all of the above. Then they watch a video to refresh. If the video is nonsense, they’ll know right quick. They’ll assist many times before they take lead, and will take lead with a supervisor many times before ever going solo.
The headline makes it sound like someone is watching a YT video and then walking into the OR to perform an operation.
