This is a question that is asked by everyone, up to and including politicians who will have to tackle any future such crises. Pre-Y2K I worked to fix loan systems that would have failed had their Y2K bugs not been fixed. Not getting a loan isn't accidentally launching a nuclear missile, but it affects your credit score and stops you buying a car. Enough of this kind of failures would have had a severe effect on the economy, up to and including causing an economic crisis.
