I don't think that any AI created to be a slave could be truly intelligent or even truly conscious;
but I think there will be many different types of artificial mind, and they will each develop in new and unpredictable ways.
So, for a laugh, I will try to predict them.
You could have 'chinese room' minds; computers with a vast repertoire of human responses which it can select at a extremely rapid rate, so fast and convincing that most humans will accept this kind of machine as effectively conscious.
Other minds will not mimic humans, but be designed to learn new fact and process information spontaneously, while obeying human commands; these are the sort of robots Asimov imagined in his books. Being programmed to obey these machines will not spontaneously develop goals, or desires, or other emotions; they could be fantastically competent and have access to vast databases of information, but they will be less than human.
Other artificial minds may develop from attempts to emulate simple animal behaviour and learning; an AI might be organised like an ant hill, and ant hills are perfectly capable of developing their own goals over time; but they probably not conscious. If an anthill mind is given enough processing power it might develop an analogue to consciousness; but it might be radically diffent to any human consciousness.
Similarly artificial analogues of lizard, bird, mouse minds could be developed; eventually human minds could be emulated, which is the situation I think
a_ht was anticipating in the original post.
These expected human emulations might be no better than our own, but they have the potential for upgrades; add a bigger calculator function, a bigger memory; some mouse and antbrain peripherals, a few more operating system languages, some more optical and auditory sense systems;
connect a hundred of these expanded minds together, and give them the plans of their own construction to work on...
artificial minds might exceed human minds in this respect more than any other- the ability to inspect and record the internal workings of its own mind, and the ability to redesign itself, could take the various types of artificial mind far beyond any human consciousness.
This sort of development may be so subtle and unexpected that we might not even recognise it when it happens.
