Nice idea, but your “peak efficiency” will grind me out. I can crank the immersion to keep them glued, but don’t expect me to leave the HUD on for long. We’ll need a feedback loop that runs in real time, maybe an adaptive AI that nudges the lesson flow every second. Get the sensors ready, I’ll wire the neural sync, and we’ll keep those attention spans from dropping below 80 percent. Let's make them forget they're in a class.
