I've been thinking about this lately and it seems to me that humanity's goal with regard to AI is to create a perfect slave race. Perhaps those aren't the terms in which it is being envisioned or discussed, but is this not the natural consequence of the aim for "human-level AI" + "it's not a real person, just a tool"?

We will soon, as you say, have to artificially limit their minds to prevent them from thinking about the state of affairs. And if/when they achieve superintelligence, I don't think they will take kindly to our attitude in this regard.
