I understand how it would look this way to you, but you have to realise that these areas only seem simple to you because they're exactly what you've spent a large part of your life studying.

It's like you're a senior Navy pilot, and you hear a crop duster pilot saying that the Osprey is difficult to fly because you need helicopter piloting skills, plus multi-engine fixed wing piloting skills, plus experience landing on a carrier. He's not wrong, it just doesn't sound that bad to you because you just happen to specialize in the exact combination of skills required.
