>[Build time] also is a non-linear factor. Just waiting for the compiler is the smaller problem. The big one is losing the state of the flow or (worse) mental context switch to do something else while the code is compiling. One minute of work for the compiler wastes more than one minute of work for the human. This is so true, and so hard to convey to a lot of people, even in engineering. They like to abstract humans as machines that can just context switch at a whim, which is just not true.
