> They obey a specification developers know
Which spec? Is there a spec that says if you use a particular set of libraries you’d get less than 10 millisecond response? You can’t even know that for sure if you roll your own code, with no 3rd party libraries.
Bugs are by definition issues arise when developers expect they code to do one thing, but it does another thing, because of unforeseen combination of factors. Yet we all are ok with that. That’s why we accept AI code. They work well enough.

There can be. But you’d have to map the libraries to opcodes and then count the cycles. That’s what people do when they care about that particular optimization. They measure and make guaranties.
