Brain-reading tech is coming. The law is not ready to protect us.

"Nothing was your own except the few cubic centimeters inside your skull." That's from George Orwell's dystopian novel 1984, published in 1949. The comment is meant to highlight what a repressive surveillance state the characters live in, but looked at another way, it shows how lucky they are: At least their brains are still private. Over the past few weeks, Facebook and Elon Musk's Neuralink have announced that they're building tech to read your mind -- literally. Mark Zuckerberg's company is funding research on brain-computer interfaces (BCIs) that can pick up thoughts directly from your neurons and translate them into words.
