Artists, construction workers, administrative clerks, police and video game developers all develop their neural networks in the same way, a method simulated by ANNs.
This is not, "foreign to most artists," it's just that most artists have no idea what the mechanism of learning is.
The method by which you provide input to the network for training isn't the same thing as learning.
AI/LLMs can train on whatever they want but when then these LLMs are used for commercial reasons to make money, an argument can be made that the copyrighted material has been used in a money making endeavour.
And does this apply equally to all artists who have seen any of my work? Can I start charging all artists born after 1990, for training their neural networks on my work?
Learning is not and has never been considered a financial transaction.
I can't imagine who would hire him. He fucked Unity badly.
