Your definition on what constitutes putting "humanity" into a piece of art is completely arbitrary. Thus I, and any rational being, reject it.
If a human have a image in his head and put it on any media that's putting "humanity" into art. You can do it with AI, so the debate is closed for me. I've had images in my head that, after a lot of work, I've been able to put into a bitmap. The accuracy in which you can translate the image is a matter of skill as with any art of trade. But it can certainly be done with great accuracy using AI tools.
So there's no rational argument to say that AI art cannot have "humanity". Unless you start talking about "souls" or something like that.
