Test subjects in a brain-chip trial are reporting some wild experiences during sleep—surfing the web, streaming movies, even having psychotic nightmares. All happening while they're completely unconscious.

Remember sleepwalking? Now imagine what happens when neural interfaces stay active 24/7. If your brain's online while you're asleep, who's really in control? What stops someone from accessing those signals?

The security implications are massive. We're talking about direct neural access—no passwords, no two-factor authentication. Just raw brain activity potentially exposed to external interference. The line between human autonomy and hackable substrate is getting terrifyingly thin.
