Center node: "solidarity should be a core ethical principle of ai"
  Abstract: Solidarity is one of the fundamental values at the heart of the construction of peaceful societies and present in more than one third of world's constitutions. Still, solidarity is almost never included as a principle in ethical guidelines for the development of AI. Solidarity as an AI principle (1) shares the prosperity created by AI, implementing mechanisms to redistribute the augmentation of productivity for all; and shares the burdens, making sure that AI does not increase inequality and no human is left behind. Solidarity as an AI principle (2) assesses the long term implications before developing and deploying AI systems so no groups of humans become irrelevant because of AI systems. Considering solidarity as a core principle for AI development will provide not just an human-centric but a more humanity-centric approach to AI.

Connected through hyperedge HE-1 (induced by source paper "ethics in the digital era"):
  with members:
    - "the role of artificial intelligence in achieving the sustainable development goals"
    - "the global landscape of ai ethics guidelines"
