Exactly right, and there's an even more compelling reason. Consciousness is hard and motivation is hard. I'm convinced it's easier to create a neural interface than write a truly intelligent program, so all of that superintelligence will simply be add-ons to your average human, driven by a human, with your normal human feedback loop (physical sensations, emotional needs, etc).
Why are we afraid of AI? Because it can sift through thousands of computers near-instantaneously and collect the data it needs? Because it can control physical machinery halfway across the world?
We can do all of that. And with the right upgrades (which, again, are probably easier than inventing a conscious machine), we'll be able to do it as fast and as well as any machine.
