Companies are pouring money into AI but failing to translate that investment into workforce capability, largely because traditional training methods don’t help employees retain or apply complex skills. Extended reality—virtual reality, augmented reality, and mixed reality—bridges this gap by letting people learn through immersive, emotionally engaging, hands-on experiences that the brain encodes like real events. Organizations from Bank of America to Boeing to Walmart are already seeing faster learning, higher confidence, reduced errors, and lower costs by using XR to train employees in everything from customer-service scenarios to technical assembly. The technology works because it aligns with how people actually learn, benefits from major improvements in affordability and accessibility, and meets the expectations of a workforce already accustomed to immersive digital environments. The companies that start with focused pilot projects, match the right XR tool to the right skill gaps, and scale deliberately will build training systems that actually change behavior and materially improve performance.
