Except it's not. Traditional algorithms are well understood because they're deterministic formulas. We know what the output is if we know the input. The surprises that happen with traditional algorithms are when they're applied in non-traditional scenarios as an experiment.
Whereas with LLMs, we get surprised even when using them in an expected way. This is why so much research happens investigating how these models work even after they've been released to the public. And it's also why prompt engineering can feel like black magic.
I think the historical record pushes back pretty strongly on the idea that determinism in engineering is new. Early computing basically depended on it. Take the Apollo guidance software in the 60s. Those engineers absolutely could not afford "surprising" runtime behavior. They designed systems where the same inputs reliably produced the same outputs because human lives depended on it.
That doesn't mean complex systems never behaved unexpectedly, but the engineering goal was explicit determinism wherever possible: predictable execution, bounded failure modes, reproducible debugging. That tradition carried through operating systems, compilers, finance software, avionics, etc.
What is newer is our comfort with probabilistic or emergent systems, especially in AI/ML. LLMs are deterministic mathematically, but in practice they behave probabilistically from a user perspective, which makes them feel different from classical algorithms.
So I'd frame it less as "determinism is new" and more as "we're now building more systems where strict determinism isn't always the primary goal."
Going back to the original point, getting educated on LLMs will help you demystify some of the non-determinism but as I mentioned in a previous comment, even the people who literally built the LLMs get surprised by the behavior of their own software.
That’s some epic goal post shifting going on there!!
We’re talking about software algorithms. Chemical and biomedical engineering are entirely different fields. As are psychology, gardening, and morris dancing
Yeah. Which any normal person would take to mean “all technologies in software engineering” because talking about any other unrelated field would just be silly.
