Well, it's actually a rant about AI making what the author perceives as mistakes. Honestly it reads like the author is attempting to show off or brag by listing imaginary mistakes an AI might have made, but they are all the sort of mistakes a human could make too. And the fact that they are not real incidents, significantly weakens his argument. He is a consultant who sells training services so obviously if people come to rely on AI more for this kind of thing he will be out of work.

It does not help that his examples of things an imaginary LLM might miss are all very subjective and partisan too.
