We missed out on a golden opportunity to redress the wrongs done to us by the Gods at Babel. Different languages ensured that we will not be able to build the Tower of Babel. But surely the grammar was codified long after the languages themselves evolved to a quasi-steady state. SO WHICH IDIOT INVENTED IRREGULAR VERBS? Or perhaps Gods introduced to ensure that people may never master each others' language and make another attempt at Babel.
Frustrations in learning new language apart, I think that the Tower of Babel was the noblest endeavour that (hu)man ever attempted: the tower was dedicated to the glory of human beings; what could be nobler?
