Is it ethical to use AI to replace human jobs?

AI is becoming more and more prevalent nowadays and although it's still in the prototype phase, it has been shown to out-do lawyers in court, help solve issues that groups of doctors could not, predict stock market changes better than the best stock analysts, and many online jobs can by fully done utilizing AI. It's getting to the point in society where there are fast food restaurants, Amazon stores, and more are becoming fully automated. There may be a future in which humans don't need to do a single thing and we sit back and let robots and AI handle everything for us. So my question is... Where does it stop? Should we adapt to the times? Or are we taking things too far with AI?
