I think that a BCI is a pretty dull end goal to limit ourselves at. I'm talking complete conscious/electronic integration. A virtual space in which is encoded the consciousness of a being who then creates the electronic environment through which the consciousness navigates or experiences cascades of events.
Now we're talking!
BCI isn't an end goal, it's a landmark. And moreover, a process. We already have consumer-level EEG-like systems, although they aren't quite as cheap or precise as a mouse yet. It should be possible to analyze a brain, determine the weight vectors for each neuron's connections, and reproduce it digitally, without need for a physical brain. So...I guess I just don't see the point of using genetic engineering to get there.
The question with that, though, is to what degree are we willing to invade our own existence for the sake of virtual experience. With decent mapping software, it should be possible to generate the experience of 'blue' or 'cow' on demand with electrical or even magnetic stimulation, bypassing vision entirely. Would you prefer that over a laser drawing a blue cow on your retina? It would certainly be quicker and more resource-efficient, but what is lost?
Alternatively, what is our goal in this transcendence? Is it to complement our humanity, to bring out the best parts of being human while making history of the worst parts? Or is it to become something more? What will be our motivation then?

or perhaps, much more likely, something absolutely NOTHING like this at all XD
You're on the right track. Just make sure you read carefully and do your best to understand what's going on :p
