Based on what I've empirically seen out in the world most people posting AI art are not using the same filtering as the author of this test. Plus the human choices used probably skew more towards what people think of as classic AI art than all human art as a whole.

The test was interesting to read about, but it didn't really change my mind about AI art in general. It's great for generating stock images and other low engagement works, but terrible as fine art that's meant to engage the user on any non-superficial level.
