> To ensure developers are context-switching, recompilation should take at least 20 seconds. I'm now wondering what languages and projects the author has worked on if they expect compilation to take less than 20 seconds. Maybe small-ish golang projects? I don't remember the last time I worked on something interesting where recompilation was always under a minute...
So you either worked on the biggest codebases in the world
Or youre doing CPP :)
