Saying stuff like this about any AI company is silly and makes critics sound more like stochastic parrots than AI models themselves.

Anthropic hasn't even shipped an image or video model. What is "stealing art", the fact that AI models are trained on data? What constitutes stealing in that?

I would probably consider books to be a form of art.

Art is very varied, its not just paintings or photographs. Video games can be art, music can be art (artists!), an eloquent dance can be art.
