2031: every valve, turbine and inspection in one navigable reality. New engineers walk the plant in XR before they walk it in boots; the twin flags drift long before the alarm.
Outcome: institutional knowledge survives retirement; attack surfaces mapped visually; downtime planned, not suffered.
SMILE: Map reality first — the plant is the documentation.
Grounded in: our Smart Plant hydro digital-twin report (with ASGI, 2025–26) — reality capture, Unreal XR, security surfaces.
