You won't have a working human brain emulation, but that doesn't preclude some other form of general intelligence with different emotional drivers being developed.
An older but still popular view of the human mind separate the brain and body as two parts. And we also like to separate emotions and intelligence. From my amateur understanding that does not correspond to modern neuroscience, it is all a very integrated system. We usually like clear and separate categories instead of fuzzy complicated integrated systems.
Those are two very different goals and I don't think one is necessary to achieve the other.
