Chatbots aren't failing us, our expectations for them are

All machines built prior to the computer were designed to serve as an extension of the human body. Think of things like the crane, the bicycle, and the butter churner. The computer was the first machine built to expand the human mind. The interface has changed over the years, but the goal has remained the same: to develop a machine that can perform intellectual tasks better than a human, just as a forklift lifts objects better than human arms do. To date, we have not built a machine that can perform every single function of the body at once, and we also have yet to develop a form of artificial intelligence that can effectively do all that a human brain can.
