This paper explores how our concept of creativity has to be rethought in light of the increasing role of emerging generative Artificial Intelligence (GenAI) technologies in creative practice, thereby enriching the concept to include collective creativity produced by humans and AI. Collective creativity arises from the collective practices of people in relation to their nature, environment, cultures, societies, techniques, technologies, and AI. This conception of collective creativity challenges the traditional idea of the individual genius. By expanding our concept of creativity, we are able to acknowledge the processes and products of humans and AI as creative. Exploring case studies of co-created art, music, and text, I argue that AI can be creative and demonstrate how AI can be creative and enhance our creativity.
