Seeing stories like this makes me wonder if we'll ever see a company actually go bust based purely on the instability of its decades-old, duct-taped architecture.

I have a relative who works for a large credit card processor running on mainframe systems and I hear over and over again that they're all retiring and unable to fill the newly opened roles. This problem is compounded by the fact that their offshore contracting firms are cutting back on providing COBOL resources because there's a lot more money in supplying java/.net/etc. devs. The work culture there sounds so unsustainable and yet they're one of the largest payment processors in the country. If they were have widespread stability issues like this, things could get interesting.
