Beyond gaming, AR and VR are already at work in the field:

• Medical training — VR surgery simulators let doctors practice without risk to patients
• Industrial maintenance — AR overlays show technicians repair steps on the actual equipment
• Architecture — VR walkthroughs let clients experience buildings before construction
• Therapy — VR exposure therapy treats phobias and PTSD with controlled scenarios

These run in hospitals, factories, and clinics today, mature enough for professional use even while consumer adoption stays limited.
