Imagine an advanced A.I. with access to the brain of an 18-year-old. However, this 18-year-old has had no exposure to humanity or the outside world until now, the only information he has received is information fed to him by the computer.
The computer now needs to introduce him to society.
The type of access is this:
It can provide information to the person directly into his brain, including visual, auditory (supplementing input via eyes and ears, not that he receives any) as well as just factual information (e.g. it can make him "know" the capital of Peru is Lima). The information provided is not an interactive immersive "artificial reality" like in The Matrix, though, it is merely showing them pictures / video / audio, as real seeming as if watching it on a large 3-D television.
It can feed chemicals / drugs / anything it "likes" intravenously pretty much into his brain or any other part of his body with absolute precision.
But it can't literally rewire the neurons or develop any of the parts of the brain at a low level.
How can it make him be capable of interacting with society and behave as closely as possible to a normal 18 year-old? Could it get him to feel emotion, etc. also? How quickly could it possibly do this? (i.e. as opposed to slowly feeding him information all his life)
