OpenAI CEO Sam Altman has launched Worldcoin (WLD), a cryptocurrency project that aims to align economic incentives and human identity. The project uses a device called the 'Orb' to scan people's eyes and generate a unique digital identity, known as a World ID. Worldcoin is designed to create a globally-inclusive identity and financial network, potentially paving the way for AI-funded universal basic income. Despite facing criticism and regulatory challenges, the project has significant potential.
