Do you actually disagree with the "minutiae was always borderline irrelevant" part or that it comes along with "making somebody money"? I pretty strongly agree with the original quote including the "possibly with software" part.
Minutiae such as tabs vs spaces and other formatting changes are pretty clearly "borderline irrelevant" and code formatters have largely solved programmers arguing about them. Exactly how to best factor your code into functions and classes is also a commonly argued but "borderline irrelevant." Arguments about "clean code" are a good example of this.
Broadly, the skills I see that LLMs make useless to have honed are the the minutiae that were already "borderline irrelevant." Knowing how to make your code performant, knowing how to make good apis that can be stable long term, in general having good taste for architecture is still very useful. In fact it is more useful now.
How is enshitification (the gradual degredation of service and products for commercial gain) even related to what's being discussed (the gradual obsoletion of a certain set of skills of an SWE)?
That's extremely reductive, and a prime example of why everything is enshittified today.
