You're right about the quality. But in addition AI, as we build it today, is task-oriented, not personality-oriented. People are trying to build cars that drives themselves where directed, not cars that decide whether or not they feel like driving people around at all.
Now, maybe it's possible that a task-oriented AI will at some point develop a personality. But there is no evidence that such a thing is possible.
The "real life" personalities we observe in nature--ourselves--did not evolve from task-oriented machinery. It was the opposite: personality and will is observable in even simple animals; a beetle directs its own actions and tries above all else to preserve its own life. No one sets a task for it.
Where does a beetle get that self-direction? Well, what is life itself? Where did it come from? We find ourselves in very deep waters; the depths of which I think AI-fearing folks don't seem to appreciate.
