Advances in AI, Internet, social media, and threats to cybersecurity jointly shape a new worldwide ecosystem for which there is no precedent.  At issue is building new dimensions, even principles, which would shape the future of international law. Toward this end, the Social Contract 2020 has been introduced, framed, and further refined in four contexts:  (a) The Riga Conference, Oct 12, 2019, (b) “2019 Policy Dialogue on Artificial Intelligence” of World Leadership Alliance-Club de Madrid, Oct 21, 2019, (c) AI World Society – Summit 2020 at Loeb House, Harvard University, April 28, 2020, and (d) United Nations Charter Day, June 26, 2020.
