Nothing of what I said implied that the boundaries should always be expected to remain permanent for any typical pair of disciplines (although there will be disciplines where that holds). There are instances where boundaries have been productively crossed and fields merged. And it's certainly more productive to try to get simpler explanations using past hypotheses between disparate phenomena – as long as no information is lost. But that doesn't remove the limitations, and the only desire here is to understand and know these limitations. That's as scientific an endeavour as any. If it's a matter of the framing that makes you sombre, consider the alternative where being a finite observer with the capacity for self-reflection such as ourselves is put in a situation where we can navigate alternative descriptions of reality, never having to terminate with a final explanation, yet always growing in personal understanding... this is what your Demon would actually be doing, for if it were as powerful as you imply, it would not be a scientist at all. It would simply be reality, with these observers the lesser of it.
