Ok...so prove how shit it is by giving me a single question that I can ask it right now where it will give me the wrong information.
Your point is entirely reductionist: it's a "glorified search engine" that processes all of the search results with a breadth and speed most people either cannot or will not (due to time constraints) do, in seconds, and then gives an answer that is superior to any of the individual sources it bases that answer on.
It also expresses that answer in highly adaptable ways: e.g. it can express the final answer in a way suitable for a child or a postgraduate expert, or a person who learns best through answers written in a style that combines Norse Sagas and Shakespeare.
