This is what wishful thinking looks like. The author is probably proud of their architecting skill so they think it's irreplaceable. If they were good at, say, optimization, they would think optimization is irreplaceable.
I think that's just in the nature of these tools. They are better at doing things you can't do (most of the things), but worse at the things you can do (very few things).
Ex: If you're a lazy typist like most, then a code assistant can speed you up significantly, when you use it as an autocomplete plus. But if you're a very practiced vim user and your fingers fly over the keyboard, or a wizard lisp hacker who uses structural editing, then a code assistant slows you down or distracts you even.
Or as Marc Andreessen said, being a VC is the last job AI's will be able to replace :)))
> Andreessen said that venture capital might be one of the few jobs that will survive the rise of AI automation. He said this was partly because the job required several “intangible” skills and was more of an art than a science.
