There is a lot I disagree with here so this is probably going to turn into a stream of consciousness kind of thing. Humans are evolving all of the time and art evolves at the same rate. It's hard to say that art is superior to art from before, but it definitely changes. Any film student can say that movies were better in the 70's but back then the director had to be 100% positive that the audience knew what was happening. Today movies have to be quick and changing a lot so that the audience is continually intrigued by what's happening. The themes of art from and now is equal but the form is different. If you want to learn more about this I suggest this book. The speaker in the video seems to push for some kind of objectively good art to be attained. In my mind though, that goes against the definition of art. Art is anything that changes the emotions of the viewer. The speaker doesn't want art, he wants sport. Art isn't a competition between artists to create the "best art".
