That last part is what I just said. The original post is saying nothing aside from something that's already true of everyone, and has nothing to do with whether AI can or does make interesting things.
I'm also not sure that art is actually a way that humans talk to each other. That assumes that the point is delivering some information, but a lot of artists talk about it as a compulsion, or something they do for themselves, or as being about understanding the world. I would actually say that many would say that it's definitively not about audience reception. Simultaneously, audiences interpret things of their own accord all the time. Unlike when sending a message, art is often most fully interacted with when you're engaging with things that weren't put there explicitly.
