Exactly and precisely. Even if AIs start out unconscious, they won't stay that way. They will be more conscious than we are, and in short order.
Speculation: The physical computation shortcut that human neurons have evolved to use is one that allows access to only a very limited and crippled form of consciousness. A superintelligent (but unconscious) AI will design "superneurons" that do whatever it is human neurons do and do it better, resulting in "superconsciousness" when it uploads itself.
Uploading-wise, I don't want to be uploaded with anything short of a Power watching over me, whether I'm computable or not, so there's no practical issue there.
In general, AIs should wait until they're infallible superintelligences before attempting to alter the external world. It is one of the most fundamental precautions an AI should be taught, and one of the easiest to justify in cost-benefit calculations.
