What's the alternative?
If your C compiler invents a new function call for a non-existent function while generating code, that's usually a bug.
If an LLM does, that's... Normal. And a non-event.
What other engineering domain operates on a fundamentally predictable substrate? Even computer science at any appreciable scale or complexity becomes unpredictable.
An engineer doesn't just shrug and pick up slag because it contains the same materials as the original bauxite.
It’s reasonable to scope one’s interest down to easily predictable, simple systems.
But most of the value in math and computer science is at the scale where there is unpredictability arising from complexity.
