100% generated using AI.
Everything: text, music, characters, voices, editing -- all done via prompts, using multiple engines (I think he mentioned about a dozen services involved).
I would not call it "high art", but it's definitely not a slop, it's an artist skillfully using AI as a tool.
While we're sharing AI generated videos, IGORRR's ADHD music video [0] is definitively art, zero question about it. I don't think typing a prompt in and taking the output as it comes is art -- good art, anyway (the point-and-shoot photography comparison is apt) -- but that doesn't mean AI can't be used to make truly new, creative and unique art too.
This is absolutely slop. Higher quality slop, but slop nonetheless. Ask yourself: what does it say? What does it change in you? How this makes you feel?
Artists use their medium to communicate. More often than not, everything in a piece is deliberate. What is being communicated here? Who deliberated on the details?
Those videos are as much "art" as Marvel's endless slop is "art".
