Part 13/16:
The path to a whole-brain interface involves monumental scientific challenges: achieving stable, high-density neural recordings from millions of neurons, avoiding immune responses, and ensuring data security. Musk acknowledged that full-scale, million-electrode interfaces are still futuristic, but he remains optimistic about the fundamental physics—if it doesn't break known laws of nature, it’s just a matter of engineering.
He emphasized that higher temporal and spatial resolution in neural sensing could revolutionize our understanding of brain function, from mapping neural circuits to decoding thoughts, emotions, and memories.
