I'm not saying I agree with the decision. In this recent case especially...Steven Thaler had gotten a patent for his art-creating algorithm. But he could not get copyright for the works it created.  ¯\_(ツ)_/¯ 

Personally, I think copyright has gone a little too far, and benefits large corporations more than individual artists. (Disney, I'm lookin' at you.) As for me...I have had my work "borrowed" many times, and haven't filed any lawsuits or sent any takedown requests. (Notable examples: a major newspaper swiped a photo I took to use with one of their articles, with no permission asked and no credit given. A business in upstate NY is using an image I made as their Facebook header, again, no permission asked and no credit given.) I'm not a copyright fanatic.

But I don't make a living off my art. Those who do should at least be aware of this issue.
