@clacke I think they are good arguments, if static typing takes 4 hours and boils the oceans to do the same work a dynamic program can do in seconds, then you should prefer dynamic.
The fastest static language I know is Julia, and it has a 4-60s startup time depending on what you load, even in the latest versions which are down from 120s startups by not loading as much; it's not any faster at the static compiling.
Julia's much faster than Python at runtime, but always loses from cold start.
