I don't think DDD is a silver bullet; building quality software will require DDD but it will also require more.

But don't get me wrong, I always been a proponent of keeping Domain concerns in The Domain layer.

It makes much more things easier in the long run, beginners should be exposed to DDD very soon in the learning process, in my opinion.

DDD and the principle of separation of concerns always reminds of Uncle Bob screaming "DATABASE IS DETAIL!": https://www.youtube.com/watch?v=o_TH-Y78tt4&t=42m45s
