This study examines how AI-assisted artistic practices reshape authorship, cultural ownership, and museum governance through the lens of cultural sustainability. Drawing on qualitative methods including literature analysis, expert interviews, and exhibition case studies, it explores emerging ethical challenges related to data provenance, creative agency, and institutional responsibility. The findings reveal hybrid forms of authorship that disrupt conventional intellectual property frameworks and highlight museums’ growing role as mediators between technological innovation and cultural preservation. While AI-driven exhibitions expand accessibility and engagement, they also risk cultural homogenization. The study offers strategic insights for policymakers and cultural institutions on fostering ethical, inclusive, and sustainable AI integration in artistic practice.
