I think you are right about this -- I just wanted to draw the distinction between mathematicians and the much larger population of scientists/engineers, who really do write a lot of code which is in its way "serious computing" even if it doesn't deal with any of the concerns and practices of "good software engineering". (I also think Julia would be okay with the current level of support for the "computer sciencey" technologies you describe like parser and web servers and so on -- it's pretty good at calling out to C or C++ if needed. But even many of the scientific/numerical packages don't have the maintenance resources they really need, so are often "good but flaky". This situation does seem to be slowly improving though.)
