The part that piqued my interest is that there exist neurons that code for a particular location in your field of view. So if you had a neural link implant you may be able to write software to tell not just where you are looking but what you're paying attention to.

We can currently tell where you're looking with eye trackers, but that doesn't work outside of a controlled environment where you can place a camera in front. And that is not the same as what you're paying attention to.

Imagine if your car detects a potential danger around you and could know if you've seen it already or not. Or if your IDE rearranged itself based on what you're paying attention to.

Not by itself worth the intrusiveness of an implant, but if you already have one, I wonder what we could do with it that wasn't possible before.
