Imagine a system that watches your brain waves and predicts your next move—pretty neat if you’re a chess master, but a nightmare for personal space. The line? Keep the data strictly anonymous, no linking to identity, and only allow the AI to act when you explicitly hand over control, like pressing a button. Anything else and we’re talking about a future where privacy is a luxury, not a right. And if you’re feeling paranoid, just remember: a well‑guarded algorithm can still be broken by a single careless slip.
