Elaborate code? Is he talking about encapsulating things like database and web service implementation details? Is he talking about stuff like IoC? What happens when you need to fix a bug or add a new feature. I know he says "just change what needs to be changed" but sooner or later you will run into the situation where a shared resource, like a database table, needs to be changed.... Ah forget it he is talking about incurring technical debt to ship on time. Debt is debt, you will pay the price sooner or later.
