The idea of comparing AI to “alien” is mindblowing. With the development of AI, it is no longer seen as a tool, but rather a creature that is better than humans in some aspects and even taking over humans’ self-given role as the center of evolution. A quote I really liked from the lecture is “AI has hacked the operating system of human intelligence.” In front of AI, we are more doubtful than ever about the most acknowledged “truth” that we have been believing for centuries. For example, what is the meaning of “think”? What is the meaning of “being creative”? I used to believe that even if AI can take over a lot of jobs, the one thing that it can’t replace should be creativity. However, the lecture and the performance of AIs today make us doubt: What is creativity anyway? Even humans themselves are not fully conscious of being creative. So, it is possible that AI is actually redefining the world from a very low-level perspective.
