I can't say with any authority on why practices are different between the different environments. So, to that end, I should have offered it as /a/ reason, as I don't think it is the sole one. I can't shake that it contributes, though. I mainly meant it is a counter to the implicit "devs at office job are too lazy to learn different ways."

For other examples, I would dip into major logistical simulations/optimizations. Which basically drop into linear algebra as soon as they can, where much of the idea of typing is basically thrown out, so that we can solve equations and constraints, with no real tracking of which is which at different locations. There is a tranlation in/out, but once in, things are effectively "matrix of values.

(As an amusing aside, I love that I get to message with the authors of books I'm reading on places like this. I have your Crafting Interpreters. Working through it at a glacial pace. Plan to pick up the other one next. Kudos and thanks!)
