you are being wildly optimistic. AI confidently lies to you about purely objective things such as asking it to write a program and it confidently writes it wrong and tells you that it is correct over and over. Something like psychology and mental health is far from objective and is constantly evolving, and also differs from person to person based on a gazillion different variables, the most important of them being emotion, something a robot will most likely never have. Even some living animals do not have a wide range of emotions such as snakes that only feel fear and anger, they don’t feel sadness or happiness or anything. What would make you think that artificially created robots would have enough emotional intelligence to replace human psychologists within 5 years?
