"Anybody who ever lighted a fire without matches has probably gained some proper respect for "low" or "primitive" or "simple" technologies"

It's true. I remember building my first bow-drill and spinning up an ember to blow to flame in a nest of tinder. And the bow, spindle, fireboard, handhold, and tinder bundle all need to be designed just so. Making fire *IS NO SMALL THING*!
