Brain-computer implant technology is rapidly advancing with increased clinical trials, expanding applications beyond paralysis to mental health, and a surge of startups, especially in China, driven by regulatory approvals and investor interest, signaling a significant growth phase by 2026.
Researchers at Stanford have developed a brain-computer interface that can decode inner speech from neural activity, raising both exciting possibilities for communication for those with paralysis and significant privacy concerns about mind reading without consent. The system can interpret imagined words with over 70% accuracy, but also risks unintended thought leaks, prompting calls for safeguards and regulation to protect mental privacy as the technology advances.
