Okay, I get your point.
However, I personally agree with the author and I don't think his argument is necessarily motivated out of an anxious fear. On the contrary I think it may be motivated out of a sense of extreme exhilaration and empowerment.
Because experts (like myself as a programmer for 15+ years) who are using AI in many fields are suddenly empowered and much more useful than we were before AI. My employability and value has gone up and not down, precisely because of being able to apply my expertise with AI, which people without expertise simply cannot do. I am a professional programmer and also owner of my own startup.
Let me give you a concrete example that I am dealing with at my startup. I'm a small business owner. Before AI if i wanted to produce production quality video for marketing it would taken such a huge budget and such a large team of people (or an expensive agency) that I wouldn't even have considered it due to the enormous cost. I'm talking about Apple quality video production which takes millions of dollars to produce.
Not anymore. A single competent person with AI can replace an entire marketing video production department or agency. But expertise is key here: knowledge of film terminology to be able to describe the effect you want, and ability to use video editing tools effectively, as well aesthetic taste. I as a programmer with no filmmaking experience don't even know how to write the prompt which makes the video that i want because I don't even have the terminology. But a person with that expertise has suddenly become more employable and more valuable to my business because I as a small business now have the capability to create Apple quality marketing videos.
So AI actually created a new job for an expert that would have otherwise not existed because it was outside the budget of small businesses. Previously somebody like that would have been employable to only a few large production studios but now they become employable by almost any small business.
