Step down approaches have been working just fine for decades. It just takes a real pilot to transition to the final landing phase to make it work properly. Push button pilots running a computer might not find it easy because they are not real pilots, just push button pilots. Blast away.
There's plenty of ill-informed drivel to go around on this forum, but that takes the cake! Time for you to do some reading. I suggest you start with the ALAR (approach and landing accident reduction) toolkit created by the Flight Safety Foundation with assistance from pilots, manufacturers and aviation authorities. Among the highest accident factors that led to the initiative was the dangers of step down approaches. Even "real" pilots have killed themselves doing a step-down approach.
