This editorial explores the transformative role of generative artificial intelligence (AI) in augmenting human creativity and catalyzing cognitive evolution. Tracing its historical lineage from symbolic AI to transformer-based architectures, this editorial argues that generative AI is not merely a computational tool but a cognitive partner that reshapes our understanding of creativity, perception, and epistemology. The phenomenon of AI hallucination—often dismissed as error—is reframed as a window into the dynamics of both artificial and human cognition. Through technical and philosophical analysis, the paper discusses generative AI’s impact on fields ranging from art and architecture to scientific discovery and education. The article also interrogates the ethical, societal, and metaphysical questions raised by AI-human symbiosis and proposes a vision for a co-evolutionary future beyond hallucination, where creativity emerges from collaboration between minds—both biological and artificial.
