No, I'm not going all "New Age" on you, this time I'm looking at how computers are going to get a 3rd dimension and how this will change the way we interact with them. The previous parts of this series have been based on extrapolations or previous history. This time I'm looking further forward, when technologies currently in long term development become available and open up a whole new realm of possibilities.

"Neural interfaces allowing direct interaction with computers at the level of abstract thought will replace any need for an "interface", and are likely to render a brain an electrofied puddle of goo."
Yes, neural interfaces are progressing, but the actual ability to decode the numerous electrical impulses of the brain, to re-represent them, and to re-transmit them through the brain which will always simultaneously have natural, non-artificial electrical activity in any meaningful, non-destructive manner is a long way off.
Attempts to re-represent visual information is advanced when the subject is a fruitfly. When it is a human, a neural interface is capable of producing some connect-the-dots phosphene activity that can "suggest" the most basic visual cues; however, anything sophisticated, visually, is difficult to re-represent as electrical impulses that can be understood by the brain.
