This is almost, but not quite, Eliezer Yudkowsky's modified
version of the "Moravec Transfer" (first described in Hans Moravec's
1988 _Mind Children_): see http://sysopmind.com/singularity.html .
However, the Moravec Transfer, and Yudkowsky's variant, both
accomplish the transfer without creating a duplicate. There
is a single consciousness (the most vivid form of this Gedanken
experiment is performed while the subject is awake) whose
physical substrate is gradually replaced while the subject is
reading _Cosmopolitan_, or watching daytime TV ;-> .
The "reasonably good imitation" part happens neuron by neuron;
after this is achieved, the biological neuron is cut out of the
network and the simulated neuron patched in, without the
conscious awareness missing a line of dialog of _General Hospital_.

This has been done by Greg Egan in the 1990 story "Learning To Be Me",
published in the 1995 collection _Axiomatic_. In this story,
every human receives a "jewel" (colloquial for Ndoli Dual),
a neurocomputer which learns to be that person as the person
grows up. The creepy part of the story is that replacement
of the biological brain by the jewel doesn't wait for the
human to perish; it's done in early maturity (early 30's).
"I was six years old when my parents told me that there was
a small, dark jewel inside my head, learning to be me."
This story reminds me very much of the old (1964) _Twilight
Zone_ episode "Number 12 Looks Just Like You"
