I disagree - it's only when you try to take ideas out of the textbook and put them in the real world where it is relevant to people that you run into the messy details that make or break ideas.
If the ideas are about purely intellectual things, that's fine.
But if the ideas are about people's lives or actions, or any complex system in the real world, then the idea isn't really fully fleshed out until someone starts to implement it.
