Earlier quoted context omitted.
LLMs are still very young. We'll get there in time. I don't see how it's any different than optimizing for new CPU/GPU architectures other than the fact that the latter is now a decades-old practice.
Not to pick on you, but this is exactly the objectionable handwaving. What makes you think we'll get there? The kinds of errors that these technologies make have not changed, and anything that anyone learns about how to make them better changes dramatically from moment to moment and no one can really control that. It is different because those other things were deterministic ...
And while the kind of errors hasn’t changed, the quantity and severity of the errors has dropped dramatically in a relatively short span of time.
