Thomas Hartung and colleagues | The future of organoid intelligence | Frontiers Forum Deep Dive 2023

Human brains outperform computers in many forms of processing and are far more energy efficient. What if we could harness their power in a new form of biological computing? In this Frontiers Forum Deep Dive session on 21 June 2023, Professor Thomas Hartung, Dr Lena Smirnova and other renowned researchers, explored the future of organoid intelligence and the scientific, technological and ethical steps required for realizing its full potential. The session brought together the authors of the Frontiers in Science lead article ‘Organoid intelligence (OI): the new frontier in biocomputing and intelligence-in-a-dish’ which presents a roadmap for the strategic development of organoid intelligence as a scientific discipline. It was attended by hundreds of representatives from science, policy, and business across the world.
