It's a futuristic idea with a high risk when you talk about implanting a chip to a human brain. Kind of reminds me of a hollywood movie called "The Lawnmover Man" with Pierce Brosnan.
The sifi movie had similar futuristic ideas similar to what Neuralink is doing.
Now it's beyond me who would want to risk brain damage but Elon's goal is not to to save paralyzed volunteers but somehow incorporate it with AI and this is when it get's scary.
Now I already know how the movie ends and maybe you too should watch the movie too.
