Meh, I think the concept of interfacing directly with the brain is really interesting, I just don't know if an Elon company is the one I want doing it.
Of course I'd rather have a brain interface that I didn't have to implant though.
I agree, but even if I did have to replace it, say, once a decade, it would make the surgery much more likely to be a success. When you can control the restriction of blood flow using the bodies own mechanisms, shut off the immune response within that area to remove rejection, and control the pain with targeted painkillers all automatically, the chances of dying on the table go away down. Not to mention the possible benefits of controlling your perspective of time, controlling emotions, having a perfect memory, being able to experience perfect VR, being able to remotely control machines, learning instantly via a download, automated control of replacement/additional limbs, and elimination of exhaustion all make it pretty attractive.
I agree that the concept is interesting, but honestly the damage that could be done with something like that is just not worth it.
With corporate greed you can't be sure what weird step they decide to do next. And everything they do directly affects you.
Not to speak of the possibility of getting hacked and having a weird version of the bee movie play in your head on loop.
