You’re fixated on the very specific examples in our existing tools and saying that this wouldn’t work. Numpy could have a switch inside an operation decides whether to auto parallelise or not, for example. It’s possible but nobody is doing it. Maybe for good reasons, maybe for bad.
I’m doing no such thing. I’m providing an example of why verifiable industry trends and current technical state of the art are the way they are.
You providing examples of why it totally-doesn’t-need-to-be-that-way are rather tangential, aren’t they? Especially when they aren’t addressing the underlying point.
