I remain skeptical about anything Musk-related. He has voiced concern about AI becoming anti-human, whether it's genuine concern or a narrative to push Neuralink remains to be seen. Regardless, it'll be interesting to see where that Tech goes, I think it would be cool if we could harness it to achieve hivemind. Imagine all the pedes in the world connected "telepathically". There will probably be 'collateral casualties' before it becomes anywhere robust enough though. That said, as others have mentioned, I wouldn't implant any device on my brain unless it's Open Sourced and I have full control; if they want to be able to shut down your smart car, imagine what they'll do to your brain.
