Poetry is the poet's reflection on life, and poetry is an outlet of his feelings. Poetry is an aesthetic, and the poet wants to share his understanding of beauty with readers and find a bosom friend. Poetry is a way for poets to get rid of loneliness. From this perspective, poetry is a very personal art. Therefore, although poetry can show talent, it is generally insulated from fame and fortune. The most direct evidence is that you can't enter the official career with poetry.
It is not that poetry needs us, but that we need poetry. As long as human beings have emotional activities and aesthetic needs, there must be poetry.
As for the quality of poetry, anyone's subjective assumptions are unscientific. I think what most people like is good poetry. What can be widely circulated is a good poem. What can be affirmed by history is a good poem and a masterpiece in poetry.
