The sixth-generation (6G) wireless networks aim for a shift towards an AI-driven infrastructure, supporting critical Internet of Things (IoT) applications with extraordinary performance requirements. Ultra-Reliable Low-Latency Communication (URLLC) plays a key role in this vision, but its demanding criteria challenge traditional communication principles. This paper argues that Goal-Oriented Semantic Communication (GOSC), a new approach focused on transmitting only the essential information needed for a specific task, is vital for enabling URLLC in 6G. We examine the primary research challenges associated with processing, knowledge sharing, and resource management. A comprehensive, AI-centered architecture with a dedicated semantic layer is proposed to address these issues. Through case studies in industrial automation, autonomous vehicles, and remote healthcare, we demonstrate GOSC's potential to significantly reduce data loads while improving task success. The paper concludes with future research directions, including standardization, security, and developing a complete theoretical foundation for goal-driven information
