How would be a world without art? The cars are designed by artists and people drive them listening music on the radio. Journalists are also artists, they provide content. How would look a photograph without any idea about the contrast or the composition? These are not merely technological issues. In fact it is about understanding proportions, which is the automatic mathematics, that can be perfected by the practice of visual observation.
In a discussion that was aroused among the public during the last president election in Finland in 2012, someone was in fact claiming, that musicians and artists are unnecessary for the society. However, as I already stated, arts and music have been a great part of civilization from ancient times, and there is no way to claim, that human kind could exist without these creative actions. Being an artist is not taken as a proper occupation, but in which sense, let's say for example telemarketing, is a more proper occupation?
