I bristle whenever people want to lay the word art on more things. I see it as an extension of so much of the infantilized culture (speaking from the US) we live in. Seeing yourself engaging with art is much more flattering than acknowledging the potential juvenile nature of what you may actually be doing or the higher pursuits you could otherwise be chasing. It's a failure to acknowledge the distinction between art and commerce, art and entertainment.

The message of maturity can be redirected to a quote, as cited by C.S Lewis whom states:
“Critics who treat 'adult' as a term of approval, instead of as a merely descriptive term, cannot be adult themselves. To be concerned about being grown up, to admire the grown up because it is grown up, to blush at the suspicion of being childish; these things are the marks of childhood and adolescence. And in childhood and adolescence they are, in moderation, healthy symptoms. Young things ought to want to grow. But to carry on into middle life or even into early manhood this concern about being adult is a mark of really arrested development. When I was ten, I read fairy tales in secret and would have been ashamed if I had been found doing so. Now that I am fifty I read them openly. When I became a man I put away childish things, including the fear of childishness and the desire to be very grown up.”
