It's like listening to a symphony orchestra and trying to write out the sheet music that they used.

Which, surprisingly, is infinitely easier for a human to do than for even the most powerful of computers and most advanced algorithms. There's something downright magical about the way the human brain picks out sounds and images (especially those related to language and music) that computers can't quite touch yet.

I'm looking forward to the day when things like speech recognition, language translation, and music transcription really can be done properly by computers. All sorts of other amazing technologies are going to appear as a result of that, stuff we haven't even dreamed of in sci-fi movies yet.
