The flip side to this is that Julia is a great general purpose engineering calculator and simulator. For example, calculating friction in hvac ductwork, voltage drop in long electrical circuits, solar gains for windows or solar panels facing various directions, cost/benefit analyses of thicker or thinner roof insulation and so on... these are all 1 to 10 lines of code so there isn't a big porting cost in moving to Julia and in exchange you get a fast, ergonomic and sane language with universal support for physical units [1] and unicode variable names [2] so things are much less verbose than they would be in, say, Python.
In the past I used Calca [3] for these kinds of things, and there are many of these "fancy calculator apps" around, but it's just so much nicer to work in a real programming language.
