I agree with this. I think the advanced topics present tremendous value down the road. But are hardly of value in the beginning of someones journey. Think, explaining generics to a new C# developer. The best analogy from life I can think of is teaching how to play a card game to someone and whilst explaining the rules, you introduce strategies. The strategies are incredibly useful. But only serve to muddle the learning process. Possibly to the point of quitting.
