In all seriousness, modern surgeries involve a team of doctors. By design, any "first" surgery a surgeon performs is alongside several other surgeons who have years of experience not just with surgery-in-general but with whatever that particular surgical procedure is.

Same with airline cockpits. Even if the movie trope of the pilot and co-pilot both going unconscious during a flight, the remainder of the flight crew has the skills and experience to land the plane without incident.

So....yeah, turns out professionals do things the exact opposite way Musk "runs" Twitter.
