That is all it can do anyway, and yes it could be wrong. It will have all the data that you could have, of course it can process it a lot better and give a much better result, so the answer could be "it can be better trader than I could be" is true, that's not really wrong, but the fact that people expect it to be right all the time is just not understanding the market.
If you know about the market, you know that even the most likely things may fail and when you expect something, just the opposite could happen. Even if we are talking about just a bad news which could change everything. Which is why AI could be better than me, but not without its faults.
When you use a calculator does it count better than you? May be for some people it does so, but it doesn't count better than a human being, it does it faster and for that was invented. But wait, abacus was invented for the same and it is a good helper in counting as well! AI is a good tool also but expecting it will be better than a human... hardly! Than some people... may be... and may be these people should not play in trading at all not to lose nor with a help of AI nor themselves, right?
