e.g. Building a hut, with cross-bracing so the square-lashed frame doesn't collapse in a light breeze.

Or hanging the ridgeline of a shed roof from a post so it doesn't push the walls out of line.

Or building a truss for a bridge over a creek, instead of a huge arch of stone.

Lots of places statics comes in handy. And we take it for granted, that we know this stuff!

Oh, that static analysis. I, um, was thinking of something else with the same name. Yes, knowing how to build things that don't fall down is pretty fundamental.

You gotta have `lint` in a post-apocalyptic world though.

Yeah, it's useful for starting fires.

Little known fact: Rome collapsed because they did not use a language that was amenable to type-checking.

Thankfully Rome 2.0 didn't make the same mistake. https://rome.tools/
