An engineer has been shot, he was working on creating AI. His neural connections were broken and some kind of robot helped him to repair neural networks. The robot has micromanipulators each of which could split into two which were twice smaller (like a recursive tree structure), then he started to work on AI, created brain-computer interface through these manipulators. Then, using this brain-computer interface with help of the robot he created AI. And they started to share mind with this AI through the brain-computer interface.
Meanwhile, the engineer was becoming more and more senseless while the robot (AI) instead started to be more and more human.
I read it about 5 - 10 years ago. It was quite short I was able to print it. And in my opinion, at that time, it was new.
PS: Some american scientist with a Japanese last name was editor of this book.
