Astor Nummelin Carlberg presents in this session the potential of open source in the context of EU digital policy on AI, and how it can revolutionize the society given the rapid technology development field as AI. Astor also describes the flip side in making open source AI mainstream. While policy makers speak about the potential of AI to bring about digital transformation and evolution in Europe, the way these technologies are developed is not always known or understood, and this especially goes for open source.
