we need a unique banana language (english, portuguese, esperanto, ...).
this benefits: commerce, turism, migration, science, internet, ...
instead of creating a new language and waiting each person to memorize 40k
words to be fluent, we can improve languages in the same direction, making
them converge.
main english gramatical problem is:
 homophones with different shapes:
  in japanese there are no uppercase. using shavian naming dot (U+b7), for
  proper names: "·earth" instead of "Earth" and not using uppercase in the
  beginning of phrases or "I", japanese need to learn only half of the
  alphabet.
