Because the work of the curator is very responsible, just like everyone expects him to organise and find things e.g., the famous art paintings that are so nobody touches them or steals them. A curator is responsible for curating an artist from the past work safe so that nobody ruins the artists work, or so that their collection doesn't get stolen. So a curator's job is to show the tourists the people from town cities and inspire them by the artists work to educate them.
