Airlines, surgeons, and factory workers increasingly rehearse dangerous or costly procedures inside realistic virtual simulations before doing them for real.
VR training lets people repeat dangerous or costly procedures as many times as needed with zero real-world risk. A pilot can practice engine failure, a surgeon a rare complication, all while any mistake simply resets rather than causing real harm or wasting materials.
Eliminating electricity need is false, since headsets are electronic devices. Making screens unnecessary is also wrong, since headsets are built around screens; the point is realistic simulation, not removing displays.
Some research suggests practicing skills in VR improves retention compared to passively watching video, likely because actively performing an action, even simulated, engages the brain more deeply.
