The author suggests that AI is _something_. That is, if you think you have a better idea of what you want to do that isn't the right question. I would say that if you actually get better than an AI based version of a product then it's actually a useful tool and it can be improved to be used. For example, if you say this is AI because a particular feature that is useful does not exist then you are actually talking about AI because someone is using it, just that it's useful. But that statement only has a part of what you mean. That is, if your idea isn't useless in the sense that it is useful in a specific way, you are simply asking how you did it. So to answer the question is: Why is AI useless for business?
