The Roman empire fell because their Roman numerals weren't a form of positional notation, so they couldn't figure out binary. Their computers were terrible.
@foone Maybe not; merchants using scales figured out early that a set of binary weights (base weight then each is double the previous) could be combined to any value up to 2x-1 where x was the largest weight. Now if some genius had figured out a way to combine this with an abacus...
@foone if they had Lisp, they’d have been fine, as addition on Roman numerals is just a normalise, a merge and a denormalise. As long as they didn’t need negative numbers, that is.
