kinda strange it took 400 years to get the type on metal rods to strike paper, when all the ingredients were around since movable type. Was it the Angstrom Problem? i.e. couldn’t work small type-set until almost 1900 but could make a chronograph for longitude which is much more complex mechanically than a typewriter. Perhaps if Hamilton wasn’t killed in the duel, he and Ben Franklin could have invented the typewriter.
