When we first see a person with paralysis walk again in a powered exoskeleton, or a patient communicate through a brain-computer interface (BCI), it feels like science fiction come to life. Yet beneath the awe lies a harder truth: what works in a staged demo often stumbles in the real world. This report explores the gap between laboratory marvels and everyday reliability by focusing on the experiences of the people who use these technologies day after day—individuals like Robert Woo, a longtime exoskeleton tester, and the early BCI pioneers who are pushing the boundaries of what's possible. Their stories reveal that the true measure of bionic tech isn't a single successful trial but consistent, long-term performance under unpredictable conditions. Below, we answer key questions about the challenges, costs, and human factors that define this emerging field.
