I understand your point, I think. c++ has an inefficient build system, and over time projects can end up with very suboptimal build systems. it's definitely worth spending time to pick the low-hanging fruit like in your example, or if possible, to choose a language that builds faster.

still, even twenty minutes is a long time to wait and see if your latest change actually works. in the foreseeable future, there will be complex projects that take a long time to build. you will eventually have to touch things that everything else depends on and recompile most of the code. people that work on these projects can always benefit from faster desktop-class hardware.
