People need to understand that humans are intelligent species and Ai was created through human ideas, no matter how developed ai gets it can't replace and take over every job. There are still jobs that can only be done by humans. For example how would you expect an artificial intelligence to lecture in a university, despite the vast knowledge it has it can't teach like a human that is very knowledgeable in that profession or field of study. The world can only get better with AI and there's absolutely no way that it can take over every human Job.
Yes, that's right. Humans are indeed smarter than AI so not all human jobs will be replaced by AI because of course AI's capabilities are also limited while humans are not. So on the one hand, the development of AI is good for replacing some human jobs and we humans don't need to be too afraid that AI technology will replace human jobs. It's just that we as humans must be able to adapt to the increasingly rapid development of AI technology because there are some things or jobs that will indeed be better with AI technology.
In addition to the example you gave about teaching at a university. Another thing that AI technology does not have compared to humans is creativity. Although AI technology can do anything that humans cannot do, we must understand that AI technology requires instructions from its users. This is very different from humans, we can create something when we get inspiration or creativity. this is because the human brain is much more complex than AI technology.
