Because that's what OP is talking about. Superstition presented as factual advice instead of the technically rigorous and scientific fact that already exists.

You're being downvoted because you don't understand this fact, or indeed understand what you're saying at all.

I'll spell it out for you: technically and scientifically rigorous facts do actually exist, even in regards to LLMs. We can, in fact, obtain scientific and objective facts about how LLMs perform. It can be rigorously proven that certain context habits affect certain tasks positively or negatively. Your argument is that none of this matters more than superstition. And you're surprised that arguing to a room full of engineers and scientists that science is dead and superstition is the one true way forward gives you negative response.

I usually don't have to worry about compiler optimisations because compiler experts do that; sometimes they appear in a thread about code and say "compiler guy here — if you write your code like this the compiler can optimise it".

And that person will be provably right (or wrong), in that context. And it'll be the same each time you run the test!

I just… ehh. You make a good point and I worry you are not wrong. It's all so different.

I like my 3D printing analogy much more than I wish I did.
