Ask HN: Should software developers weigh in on the U.S. debt limit debate?

The U.S. Treasury system is essentially a large series of software programs for making payments. Treasury officials are claiming they can't modify the software on such short notice to prioritize payments. Also, the world financial system is essential a large software eco-system that operates under the assumption that debt payments from the U.S. will be always be made and U.S. debt instruments will always be available. What would be the best way for computer programmers and software developers to validate the opinions of those who say it is nearly impossible to modify the software on such short notice and attempting to do so might have unintended catastrophic consequences?
