My first thought as well. It raises some interesting questions. Does the perfection of execution take away from the art? What if the meatbag artists were so highly skilled that they executed the same level of perfection? Does it mean different things?

it turns out someone else has explored this exact question:

As for what minimalist art "means", I think that's taking the wrong approach. It's more about how you feel when looking at it, what does it remind you of, what non verbal parts of your mind are activated?

Hey, that's me! Thanks for pointing it out!

I don't see the algorithmically generated solutions as pretty, but the hand-drawn ones seem to have almost fractal detail and are really nice to look at.
