There are definitely parallels though. eg you could swap out your compiler for a different one that produces slightly different assembly. Similarly a LLM may implement things differently…but if it works do we care? Probably no more than when you buy software you don’t care precisely what compiler optimisation were used. The precise deterministicness isn’t a key feature

It often doesn't work. That's the point. A calculator works 100% of the time. A LLM might work 95% of the time, or 80%, or 40%, or 99% depending on what you're doing. This is difference and a key feature.

With the llm, it might work or it might not. If it doesn't work, then you have to keep iterating and hand holding it to make it work. Sometimes that process is less optimal than writing the code manually. With a calculator, you can be sure that the first attempt will work. An idiot with a calculator can still produce correct results. An idiot with an llm often cannot outside trivial solutions.
