The integration of artificial intelligence (AI) into visual arts has prompted significant shifts in artistic practices, creativity, and the concept of authorship. AI technologies, such as generative adversarial networks (GANs) and neural networks, are now actively involved in the creation of art, producing works that challenge traditional notions of creativity. This paper explores the evolving relationship between art and technology, focusing on the transition from pre-AI to post-AI creative processes. It examines key case studies of AI-generated art, such as Portrait of Edmond de Belamy and Refik Anadol's data sculptures, to understand the ways in which AI tools are reshaping artistic expression. The study also addresses the philosophical and ethical implications of machinegenerated art, including questions about authorship, originality, and the role of the human artist. Ultimately, this paper highlights the opportunities and challenges AI presents to the future of the visual arts, reimagining the boundaries of creativity and artistic identity.
