A lot of companies are claiming they have some AI technology behind their products. In many cases, they do not have AI. They may have a very complex and sophisticated computer program, but that is nit AI.

If you give certain question or request to a human, a human does react to it but not 100% same ways. So, you can say if so called AI does only what you expect it too do 100% of the time, it is an intelligent program but not an AI.

AI is simulating human ...that means it must be irrational.
