I think a bottle of water and a sack of bricks are two perfect examples of effective complexity. The bottle is mass manufactured, looking the same as any other bottle of the same brand, yet the water in it is flows around in chaotic behavior; And the reverse is true with a sack of bricks.
I think the problem of authorship is a very interesting conflict. I’m always thinking about whether I or my computer is the artist, and even worse, what if I write a program that writes programs to make generative art, then which of us is the artist? I think one way of arguing is that the artist not the one who made the piece, but the one who found it, the first person/machine/thing to say “This is art.”
