Yes, jobs are essential, especially in a society with a very thin social-safety net, and it’s naïve and hopelessly romantic to think that jobs shouldn’t be a concern for university students. It’s very possible that your job after college will involve using AI to some extent, and therefore it’s important for students to learn how to best do that. But just as it’s important for everyone to know how to do basic math despite the wide availability of calculators, that also means you still need to know how to think for yourself and learn new knowledge even if AI is widely available.
This is true, If AI can completely fulfill a job, why hire you? The author gave a great example: we all have computers in our phones, but some people can do some complex calculations, why can't I? This shows that we shouldn't just use AI simply, but learn how to use it correctly to help you accomplish tasks that others cannot complete.
