LaTeX with packages like beamer. Treating documents as source code for purposes of version control, collaborative review, and separating content implementation

LaTeX with packages like beamer. Treating documents as source code for purposes of version control, collaborative review, and separating content implementation units from display units is just too important. In fact, I think this approach to document and word processing should be taught in schools from a young age, to eliminate most of the excuses people have for preferring wysiwyg enterprise tools, like some sort of hyperbolic discounting function when deciding that the short term cost of overcoming the LaTeX learning curve is not worth it in each situation (so that it ends up never being worth it under that inconsistent model of net present value of the “quick and easy” wysiwyg system).
