That's part of the future.
I'd love to be able to experiment both the physical and digital world at the same time, discontinuing my hand/eyes as an interface with the computer.
I believe it will eventually happen. I'm not exactly sure of the current state of the art, but I've seen research replacing lost limbs with robotic arms that are solely controlled by thoughts. Seen also images induced into one's vision by stimulation of the brain.
Our brain evolved with I/O devices meant to match our physical environment. As far as I know[1], we don't have any I/O device meant to convey ideas in themselves. We need to serialize our thoughts into words, images and movements to get them deserialized into other's minds. All this process is lossy and has a limited bandwidth.
Anyway, I'm not talking about things I really know, so I won't elaborate further into this. I try to limit my opinions on HN to stuff that I actually know. You can't fool anyone around here; next thing I know, a brain researcher will come and break all my ideas apart in the comments.
[1]That's meant to exclude telepathy stuff
