The targets for the AI are still set by humans, the data the AI was trained on is still created by humans. Involving a computer in the system doesn't magically make it less biased.
That's just what we need, an AI that was trained on biased data and then empowered to do whatever it wants autonomously. It's a pity we can't look to any examples of human intelligences that have been trained on biased data and then empowered to do whatever they want autonomously.
