Is it illegal to sell art made by AI?

I'm curious, could you please clarify for me - is it against the law to sell artwork that has been created by artificial intelligence? As the world of cryptocurrency and digital assets continues to evolve, I'm finding myself increasingly interested in the legal implications surrounding the sale of AI-generated art. Could you provide some insight into whether or not this practice is considered legal in various jurisdictions, and if so, what kind of regulations or considerations one should be aware of when engaging in such transactions?
