With machines like AlphaGo now capable of thinking and learning from their mistakes, we are getting closer to the dividing line between humans and machines.The question is where will all this lead? While Al enthusiasts promise us a bright future where intelligent

13、robots will be working to our advantage, these undoubted benefits also bring concerns and fears.Could machines really develop human-like intelligence? And what would happen if they did? Would thinking machines work alongside humans or threaten the existence of humans? How would they be punished if t
