This is actually a really good message, people think art is hard and extraordinary, cause they have to put an effort in understanding how we create things, the technique. There are people that are really good in math or biology, they are artists too just at another field. Оf course we can't know everything but we should never call something special just because we are not understanding it. If you understand something you can learn how to manipulate it and to create new things. If you can't read you will never understand Shakespeare, even less to interpret it.
Cheers!
