This is nonsense. The author implies importance of skill atrophy in the context of a job, and then claims that we ought to care if we "love coding"!
Jobs are vehicles for productivity. Where did we go wrong thinking that they would serve as some profound source of meaning in our lives? One of my hopes is that this societal self-actualization will be greatly accelerated by the advent of AI. We may have to find meaning in something other than generating clever solutions for the problems facing the businesses that pay us for that privilege.
On a related note, I am constantly annoyed by the notion that LLMs are somehow "good" because they allow you to write more code or be more productive in other ways. As far I can tell there is nothing inherently "good" about productivity in the modern economy. I guess general prosperity is a public good? But most software being written by most people is not benefitting society in any profound or meaningful way, and that's generally the first productivity gain mentioned. Either I'm completely missing something or people just don't want to think critically about this sort of thing.
