But during the 50 years, you are probably paying in a lot of little ways for the less robust system. In my experience that takes the form of 5 engineers working for two weeks to accomplish something one engineer could do if he/she fully understood the system. Not to mention work done fixing bugs that would never exist in the system with a solid foundation.
