Physical babies take a long time to adapt and form complex connections (http://www.urbanchildinstitute.org/why-0-3/baby-and-brain http://www.urbanchildinstitute.org/why-0-3/baby-and-brain). There are probably a lot of shortcuts one could take to train it for specific tasks. In 'The Matrix' they had developed programs that could be uploaded to a physical brain to essentially pre-wire the brain with complex synaptic connections (or so I imagine was the effect). That would be a lot more efficient than waiting 3 years just to get to the point of trimming useless connections. We may have to 'grow' a virtual brain via training to develop the basic platform, but then pre-load it with operations to save time.
