With apologies to Rush, if you choose to model for unconstrained optimality, you STILL have chosen a bias. Let's say the dearth of new babies, mechanization, watered down work ethic, and YouTube/govt welfare has causes a low-skill labor shortage. How do we fix it? The "optimal" solution is open borders.
The machine will always reflect the Bias of the developer. Someone is the puppet master. Unsupervised learning will have Bias as well. The robot will not be some Ayn Rand Objectivist, or Libertarian Party member. There will ALWAYS be a Bias.
THE question in ALL of this, is who will be able to untangle this web? Who can quantify what IS the Bias of the developer and what are the ramifications?
In a true AI system, one that writes its own code to adapt to a changing reality, it will evolve beyond the bias of the developer.
If it doesn't, it isn't true AI (i.e., it isn't built to evolve but to remain static and/or loyal to its developer).
If you have competing AI systems and one has a built-in bias and the other is built to adapt to a changing environment, which do you think will survive?
A built-in bias is a built-in error because a developer can't foresee how reality will change.
