Even while I certainly don't identify with the same love of details, I do highly value strong engineering principles and even those are under heavy attack from the LLM onslaught - why engineer something fundamentally well at the start if there it is zero cost to fix it later when problems actually show up?

I still maintain some belief that the pendulum will swing back somewhat. We're going to see over time the problems that emerge from systems designed without deep technical oversight - and this will form a new class of expertise in its own right. It will likely still come back to people with an affinity for technical knowledge and principles based design, just in a different form.
