LLMs bring new nature of abstraction – up and sideways

I think the whole context of the article is "program with non-deterministic tools", while non-deterministic fuzzing and mutation testing is kind of isolated to "coming up with test cases", not something you constantly program side-by-side with, or even integrate into the (business-side) of the software project itself. That's how I've used fuzzing and mutation testing in the past at least, maybe others use it differently.

Otherwise yeah, there are a bunch of non-deterministic technologies, processes and workflows missing, like what Machine Learning folks been doing for decades, which is also software and non-deterministic, but also off-topic from context of the article, as I read it.

I just have a problem with his use of the word "unprecedent".

This is not the first rodeo of our profession with non-determinism.
