It's true but until some extent. When you are talking about a hypervisor (like Xen), and many many subtle things depending on your CPU brand/model, it's really really *hard*, even with an LLM (and even more with an LLM hallucinating some CPU features or forgetting basic things like Meltdown and Spectre).

However I agree: to learn a topic, LLMs are providing a great speedup. As a CEO/co-founder, I have no issue to hire people without a degree if they are good at what they do. However, our biggest chances are to scout directly in universities to find motivated students (motivation >>> everything else)
