Well, that's a good example. Why would you get a DJ when you can say "Siri, play Weddings Classics"? There's no humanity involved, no skills to read the room or cater to audiences. So you get a DJ; what if your DJ thinks his job or your event is boring and generates the same playlist you could have done yourself? You need passion, you need interest, you need to be involved. Otherwise every job becomes tedious, and humanity dies.
