No, I did not change my mind, and it wasn’t a straw man :) Unfortunately it is you who seem to be lacking the requisite knowledge to evaluate the merit of my argument… Suffice to say, the various divisibility-related properties of integers are very closely related to ring theory. In the ring of integers (called Z), numbers of the form n*i for all i form an ideal (called nZ). As you can see these are the numbers divisble by a given n. Thus in the context of integers and divisibility, the term “ideal” is not some niche jargon, but in fact a crucial concept that anyone with a rudimentary understanding of number theory (which is very closely related to abstract algebra) have encountered. Of course not all of us software engineers have encountered these concepts as part of our formal education, but I would expect some familiarity from the alumni of any semi-decent software engineering college or university.
