Why can't modern people write more poems than the ancients? Like Li Bai and Du Fu?

In the Tang Dynasty, when poems were well written, you could be an official, but now you can't. Poetry at that time were all popular songs, and Li Bai had many fans at that time. There are few poems that can be sung now, and the fans of modern poets are mostly students at school or young people who like literature. At present, the pace of social life is too fast, and people's mentality is impetuous, which is not the big environment for poetry creation.
