Trippin' Through Time

I would say that it could not be AI because AI is a nightmarish MESS and no AI has the imagination and powerful vision of humans. Seriously, Hieronymus Bosch, and the numerous other medieval/renaissance artists who came up with some serious outlandish visions that they put on display through their art is the thing for the ages.

Uncreative people often claim that visions like that are the product of drugs and insanity, but often times creative people are just that... creative! Many Creative people aren't even weird or off when people meet them.

Rowan Atkinson, the creator and actor behind Mr. Bean, also did a shitload of other comedic roles (Blackadder, Not the 9 o'clock News, Man vs. Bee, etc) wrote most of the craziest scenarios you've ever seen... but when people meet him and talk to him in real life, they're surprised at just how BORING he is as a person. Weird Al Yankovic, one of the most successful novelty singers of the 80s to 2000s, is a fairly sociable person in real life and does make jokes like everyone else, but nothing would tell you that this guy can parody other artist's styles and genres to a T (and in some cases his parodies exceed the popularity of the original).

Again, people who did many of those Renaissance artworks, or early 18th century Sequential arts (such as Hogarth) packed so much detail in their works that the way many art historians look at those old paintaings not as simple still images, but more like cinema in one image. Because they were packed with so much detail that you had to spend a lot of time just looking at individual bits and parts, and many of those told their own stories.
