“Good evening, class,” said the teacher. “Before we start this introductory course to obtain your license for a Neural-VR-Enviro-Anything device, I need to show you something important.”

A holoprojection displayed:

A person in a busy subway activated their VR, replacing the environment with a forest. The device said when to move forward, backward, left, right, or stop. During the navigation, a horn honked loudly, and a vehicle crushed the person to death.

The students gasped.

“Indeed, it’s horrifying. The VR’s auto-assist failed—the highest cause of fatality in the nation. We advise using translucent mode when traveling in congested areas.”
