I enjoy the arts as much as anyone else, but the narrative that art by default is a transformative force for social good is just that, a nice marketing sleight of hands. Most art is entertainment, with a rather minuscule slice having something interesting to say. Not to say that entertainment isn't valuable and pleasurable, but there's a big gap between that and it advancing humanity.
And we're talking all realms of unrestrained creative effort here. Science, technology and stories about dragons. Opensource software as well as basement watercolorists. This is where the shiny new legos of our society come from.
This seems a little motte-and-baileyish. You start with "arts make the world a better place" and when presented with a critique you retreat towards "arts are the same as technology and science, let's treat them as one single group", which I don't buy.
It arises from the same free unpressured space in your life. It's the same step up to creation and experimentation and play. Just different mediums. Watercolor, thought, machinery... So let's not draw any unnecessary differentiations.
