Art and Rationality

What are your thoughts on the role of Art in rationality (personal or otherwise) and in the singularity?

If one wants to help in the efforts of SIAI (or other organizations) does it make sense to focus on an art form as more than a hobby?

Is it rational to pursue an art form that encourages people to contribute to a cause when there are more direct ways of contributing?

It seems difficult to receive much recognition for one’s work in art related fields, but it also seems as though one big success (say, a musician whose music was primarily about the singularity and increasing rationality) would turn many people on to the ideas.
