I disagree and I think you are interpreting "applied mathematics", "physics", and "computer science" overly literally - rather than labels for fields of study.

I disagree and I think you are interpreting "applied mathematics", "physics", and "computer science" overly literally - rather than labels for fields of study. The point in the article is that programming is no longer just Applied Mathematics, it's also very much a discipline of Engineering as well. Anyone who studies these fields should understand the difference. You are right, that these terms can apply to deep realms of human thought - but I think they are less useful terms under that definition.
