My daughter (15f) is an artist and I work at an AI company as a software engineer. We've had a lot of interesting debates. Most recently, she defined Art this way:

"Art is protest against automation."

We thought of some examples:

• when cave artists made paintings in caves, perhaps they were in a sense protesting the automatic forces of nature that would have washed or eroded away their paintings if they had not sought out caves. By painting something that could outlast themselves, perhaps they wished to express, "I am here!"
• when manufacturing and economic factors made kitsch art possible (cheap figurines, mass reprints, etc.), although more people had access to "art" there was also a sense of loss and blandness, like maybe now that we can afford art, this isn't art, actually?
• when computers can produce images that look beautiful in some way or another, maybe this pushes the artist within each of us to find new ground where economic reproducibility can't reach, and where we can continue the story of protest where originality can stake a claim on the ever-unfolding nature of what it means to be human.

I defined Economics this way:

"Economics is the automation of what nature does not provide."

An example:

• long ago, nature automated the creation of apples. People picked free apples, and there was no credit card machine. But humans wanted more apples, and more varieties of apples, and tastier varieties that nature wouldn't make soon enough. So humans created jobs--someone to make apple varieties faster than nature, and someone to plant more apple trees than nature, and someone to pick all of the apples that nature was happy to let rot on the ground as part of its slow orchard re-planting process.

Jobs are created in one of two ways: either by destroying the ability to automatically create things (destroying looms, maybe), or by making people want new things (e.g. the creation of jobs around farming Eve Online Interstellar Kredits). Whenever an artist creates something new that has value, an investor will want to automate its creation.

Where Art and Economics fight is over automation: Art wants to find territory that cannot be automated. Economics wants to discover ways to efficiently automate anything desirable. As long as humans live in groups, I suppose this cycle does not have an end.
