While I sort of agree with the sentiment of this, I really can't see any downside to learning how to do a decent mix on a pair of turntables. It helps to break things down to the bare minimums, no fx, no beat-sync, nothing. Basically, if you can pull off a great mix with just two dekcs and a mixer, you'll be fine to move forward with whatever else you choose to use.
Plus you know (and hopefully respect) where it all started / came from.
