I think this should generally be true. The aggregation performed by model training is highly lossy and the model itself is a derived work at worst and is certainly fair use. It may produce stuff that violates copyright, but the way you use or distribute the product of the model that can violate copyright. Making it write code that’s a clone of copyright code or making it make pictures with copy right imagery in it or…
>The aggregation performed by model training is highly lossy and the model itself is a derived work at worst and is certainly fair use. I mean, I've literally gotten the Superman logo in Stable Diffusion without even trying, so it isn't that lossy.
Literally if you asked someone for a recognizable outline of the strongest gemstone's iconic cut you'd get the outline and the rest is an obvious path. Humans might unconsciously, or even by choice, avoid something too similar to something they already know.
Superman's costume also uses vibrant colors. The red / blue pairing is used extensively across many logos and visual representations for the high contrast of two vibrant colors.
As I try to imagine an older child or young adult somehow raised in an environment like pop culture but through some twist absolutely unexposed to Superman or any related concepts, it isn't that far of a stretch to imagine independent invention of a strikingly similar idea. Maybe not as a first draft but in exploring a range of possible powers and automatic logos. E.G. as in the range of an LLM backed character creator for a superhero game, and then aneling the results though simulated effectiveness / fitness of hero powers, logo design, etc.
Everyone wants to think they're a special snowflake and that what they create is somehow unique as well. However we're all drawing on a huge pool of common culture to synthesize expressions which fulfill a set of constraints prescribed by the culture and the culture's influence on the individual and the moment being experienced.
In the case of Superman that's even arguably a description of the archetype. They are literally a super man. Clark Kent however, that's a little more unique and probably a Trade Mark (consumer commercial use protection) as long as such a registration is maintained.
