If they get mad it's because you're saying this explicitly to be an asshole. The essence of art doesn't have much to do with the mechanical skills for assembling pieces into a whole, though that part isn't trivial. Rather, it's about expressing human thoughts and feeling in a way that inspires their human audience. That's why AI-generated "art" is different in kind from a skilled digital artist and why it really cannot be art.

If you’ve read other threads you’ll see humans quite optimistic about how “ai” art tools have let them express themselves. And this is only the beginning of the commercialization of new tools, so I offer my wholehearted dissent that “AI-generated art” cannot be art. Style transfer has gone quiet but still my attention, for example.
