IRS990PF/SummaryOfDirectChrtblActyGrp/Description1Txt	0	In 2024 the Foundation organized a public reading group on the ethics of artificial intelligence inviting participants from diverse backgrounds to discuss responsible approaches to machine learning. The program concluded with an open challenge that called for creative proposals on how AI systems can be developed and trained in ways that respect pubic rights and promote transparency. Through this effort the Foundation encouraged dialogue and collaboration around building public trust and accountability in data-driven technologies.
