If this becomes a reality, programmers will become a lot less careful when writing the application software because of the additional level of protection. Google "risk compensation".

Typically, the critical control code is kept small and is developed to higher standards than the UI code. Often, errors in the interface are seen as lesser risks, which allows that part of the code to be developed to lower standards, while at the same time being more complex. That is at least what I've seen done in practice.
