I don't think that, one day, there will be a person or system that recognizes every object on earth from every angle, with high accuracy. Such a system would be very inefficient. In other words, a practical AI system needs to be biased. It's obvious that people who made the ImageNet dataset has collected images mostly from their industrialized (and possibly Western) world. I think the future trends of AI will be a re-trainable and verifiable system that can be biased towards a user-preferred way.
