I think the entire crew is responsible. They are also responsible for on going learning, education and recurrency. That includes reaching out to others in the industry.
But it is common for the pilots on this forum to devalue the opinion of anyone other than themselves. Passengers, crew, med crew etc are just supposed to get in and keep their mouth shut. Cant have it both ways but most of them that type the loudest have never probably been part of crewed aircraft.
