In the whole history of humanity art always is an accompanying part of the everyday life. If we follow the development of art from the Stone Age cave paintings - decorated rock shelters and caves throughout the world, go through medieval art in middle ages - a wide variety of art and architecture, and finally get to modern arts nowadays, we could say, that art is an essential part for human development. People focus on technologies because of our everyday technology-dependent life, and in the same time appreciate art, because art and science are similar - they are both fields of imagination.
