The way you talk about this AI you seem to forget that the same AI is still human like us that did everything that made it what it is today. No one is perfect when it comes to prediction and Bitcoin is another difficult something no one can boost about like is perfect in predicting
I believe you already know that AI does not rely on one or two sources. When you ask a question to an AI, it collects information from various sources and does some research before it answers. So, I think it is better than a human. If you ask a average person to predict Bitcoin price, they will predict based on their own perspective and without doing any kind of research. But when it comes to an AI, it will collect the information from various sources and provide you an answer. So, AI is likely to be more accurate than a single human being.
Yet, that still doesn't mean that it will give a "correct" answer. Obviously it will use a lot more information than a person, because it will take data from many sources, sometimes as much as millions, so that part is true, it will definitely be better than a human, but you need to remember that AI was built by a human as well, so if it was built badly, then it will give bad result as well, plus not even AI can know the future because the data we have doesn't really show the future, doesn't matter if it's AI or a human, having ALL information about the past, doesn't guarantee anything about the future at all.
This is why we are facing some issues with people trusting AI so far, and I am one of them, because I do not really have that much of a trust towards it at all. I am hoping for a better return, and AI will get better and it should not be an issue, but until that happens, we need to do better and we need to be careful about it as well.
