I think Computational Fluid Dynamics is a good analogy. Final year engineering courses now just explain the maths, and then teach how to use commercial software packages. That's for if you're working to engineering standards. But there are also animation tools using CFD, that don't require maths at all. Just fiddle with it to get the effect you want. NB. It took CFD a long time to get to this point. It predates digital computers, and has an even older overall theory (though not fully understood). We don't have that for DL.
