Straight from the Caprica pilot.
It's a much older idea than that. One of the best stories on it that I've read is by... Ray Bradbury, perhaps? I'm not sure. It's about a long dead classical composer whose personality and memories are reconstructed inside a living person's brain. He remembers his life, he remembers writing music and even remembers dying... but discovers that he can't compose anything new. Anyone know what I'm talking about?
Go see for yourself.
The complete post is quite long and just as good as this quote.
