Relax dude, all of these "djs" will get infront of people one day, trainwreck, panic, and quit. Those that don't, are DJs.
Technology may have simplified the act of mixing two songs, but it hasn't done much for knowing good music and what works with what. That to me is the ultimate DJ skill. Selecting. And there's no shortcut. You just have to listen to a ton of music all the time. If more people did that, the world would be a better place.
