So does a human brain.
Which brings us to the other side of the reasoning is that tools like Midjourney and OpenAI enable idiots (when it comes to drawing/animating ... that includes me) to create engaging artwork.
Recently generating artwork like that went from almost impossible to "great, but easily recognizeable as AI artwork". Frankly, I expect the discussion will end when it stops being recognizeable.
I hate Andreesen Horowitz' reasoning, but they're right about one thing: once we have virtual artists that are not easy to distinguish from "real" ones, the discussion will end. It does not really matter what anyone's opinion on the matter is as it will not make a difference in the end.
