The potential for AI to grow into something much more capable, unbiased and fair then any of is can be is obvious
It absolutely is not obvious. AI, especially today, is usually either generative based on past examples or evolutionary based on given goals. Both of those come with obvious and extreme bias. Bias is actually an integral part of machine learning. It's literally built into the system and is defined and controlled to achieve the results desired.
AI is and always will be biased, moreso by its creators, but absolutely by the information and frameworks provided to it. We have absolutely no idea how to approach the concept of an unbiased AI, or even defining what unbiased would look like. It's philosophically extremely difficult to define what an unbiased person would think or do.
Edit: somehow I missed that last sentence fragment. I don't think we're in disagreement of the conclusion, but possibly just the details of how one arrives at it.
