Problems of modern art

I have a few thoughts about the problems with modern art. First, modern art is often difficult to understand. Complex and abstract expressions are often used to convey the artist's intentions. Second, modern art is often difficult to understand. Art often seems to transcend commercial value, which means more education is needed for greater understanding and appreciation. Thirdly, originality is needed. Duplication and plagiarism must be avoided in art. However, compared to traditional art, it seems that originality is more strongly required. What do you think? I wonder if it's just me who feels this way.
