The FDA will not start approving clinical trials for gamers, and the use cases they would approve of, like parapalegics, are too niche for large scale development efforts. But best of luck to Musk and his neuralink.
So we might consider external stimulation/reading methods. Unfortunately, these tend to have a very poor resolution. But recently there was a company call Open Water that's been working on some kind of holographic imaging system that theoretically has single cell resolution with both "read" and "write" capacity. But while they can zero in on a cell, it seems they can't look at all cells in an area simultaneously. So intercepting and overwriting the activity of all the nerves in your spine isn't within their capacity. I don't know enough about how exactly their technology works, but it seems to me that their limitation is something about the complexity of how infrared light diffracts through the body. They can handle one spot, but more than one causes interference, or something. This is something that might be improved by improved mathematics or processing power, or maybe the ability to do a faster scan rate. I don't know if it will ever get there, but it is interesting that isn't totally off the table. One day full dive might be possible with only wearables and no implants.
Open Water is a new company and their technology is not mature. This will not emerge within ten years. After that, who knows.
