Extended Reality (XR), which includes AR, VR, and MR, has matured significantly by 2025. Lightweight headsets and smart glasses are mainstream, transforming how people work, play, and learn. Virtual classrooms, 3D product demos, and immersive entertainment redefine digital interaction. Businesses use XR for remote collaboration, training, and design visualization. In retail, customers try products virtually before buying. Social XR platforms let users interact in shared virtual environments. With better hardware, AI integration, and high-speed networks, the line between real and virtual continues to fade — creating new opportunities and challenges in privacy, identity, and digital well-being.
