Behind the Mask of AI tells the remarkable story of the development of what Buolamwini calls "the coded gaze" — evidence of discrimination and exclusion in technical products, and how her journey to combat the harms of AI began with the founding of the Algorithmic Justice League. By presenting a multifaceted perspective on both the technology industry and the research sector, Buolamwini illustrates how racism and sexism intersect with broad sectors of humanity, leaving them vulnerable in a world rapidly adopting AI tools. She reminds us that computers are a reflection of the ambitions and limitations of the humans who create them. This book is not one of easy answers, but it aims to leave the reader with questions that push us all to rethink and reshape the future of AI.
