In the future direct interfacing between the brain and technology seems likely. The rudimentary technology has already been demonstrated and Musk’s company is working on an implant meant to be a commercial product. My question is about how you see the interface eventually working. In particular I am curious about what the advantage of an implant is.
From the demonstrations I’ve seen things like typing, moving cursors, ect can be achieved with sensors applied to the body externally like an fmri skullcap or a neckband that reads vibrations in the vocal cords. External sensors are much safer to apply than a brain implant, they can be replaced much more easily if they malfunction, and they can be upgraded. I have read an article that said there are advantages to implants for people with medical issues like paralysis because the implant can offer feedback providing a more “normal” experience and interacting with specific nerves gives more precise control and less lag time. For medical applications like restoring lost function that makes the risk of surgery make sense. For the average person what advantages do implants offer over external sensors that make the risks of brain surgery worth it?

I read one good idea for a Google glass-type device. Say you wanted to repair your lawn mower. You’d input the proper program and you’d get a heads up display showing you every step. A little red dot would appear over the first screw, and if you looked around it would locate the proper tool.
But yeah, most of the other stuff is just tech for the sake of tech.
Not zero reason. Some people with certain disabilities could benefit from such a device. (Stephen Hawking for instance, was limited to about 10 words per minute with his button interface. A brain interface on a similar patient could be closer to normal conversion speed.)

Okay, but would you rather be locked in your unmoving body or get brain surgery and have motion again? Would you rather be blind and deaf or get brain surgery and have your senses back?

Your issue, as far as I understood it, was that the brain implants are pointless, cause they do nothing we can’t already do. There’s plenty current medical technology can’t fix, but a brain implant could (one day). Such as restoring sight by bridging cameras to the visual cortex; or restoring control over their body to disabled people, either by bypassing damaged nerves anywhere in the body or connecting prosthetics to the motor cortex. Are those things worth the trouble of going through brain surgery?

Why are you bringing up Musk? I fail to see how Neuralink is the killing blow to the very concept of brain-computer interfaces. Your bias is showing.
It’s true that current BCIs can’t do what I outlined as their potential benefits. Hence, why they’re potential. The technology still needs to develop before those potential benefits can be realised. Personally, I look forward to that day.
