Jeremy Paxman talking with a conservative activist on the "Year of Code" (at about 9 minutes in) announces: "But it doesn't mean anything".
By the same token you could quite comfortably argue that Hanzi, or Kanji, (or Arabic, Thai, Hindi or any of the other non-Latin derived scripts) don't mean anything. But a good percentage of the world's population seem to get by quite well using them...
(Oh yeah... and the artistic looking garbage on your big screen really doesn't mean anything ツ)
