While Neuralink dominates headlines, other **brain-computer interface (BCI) breakthroughs** are advancing:

*   **Synchron’s stentrode**: Implanted via blood vessels, helps paralyzed patients text.
    
*   **Precision Neuroscience**: A flexible brain patch restoring speech to stroke victims.
    

**Medical applications:**

*   **Epilepsy prediction** (UC San Diego’s AI + BCI system).
    
*   **Depression treatment** (deep brain stimulation).
    

**Ethical dilemmas:**

*   **Hacking risks** if BCIs connect to the internet.
    
*   **"Cognitive inequality"** if only the wealthy can enhance their brains.
    

The BCI market could hit **$6 billion by 2030**—balancing innovation with ethics will be critical.
