The system treats stories as persistent state that evolves over time through automated updates and enrichment, while maintaining human oversight and traceability.
A research paper examines how AI-generated visual content is transforming society's relationship with reality and representation, intensifying visual media's dominance in shaping public consciousness. An experiment in Bolzano, Italy revealed people's strong preference for visually striking AI-generated urban development scenarios over practical solutions, highlighting how AI accelerates image commodification and deepens societal alienation.
