Financial apps are a different story. I interned on Pay.gov in college, and then spent the first 2 years of my career at a financial software startup. The standards are much different when you're handling money (or avionics, or medical devices, or anything that's "mission critical"). And even in the finance world, the standards vary a lot depending on whether you're doing analytics or transaction processing.
But while that software will never go away, it becomes a smaller part of the whole software industry. Much of the interesting growth is in areas of software that have nothing to do with money, other than being able to make it. It's silly to apply the same standards to software that processes $10M/sec (as one program I once wrote did) as to software that lets you throw virtual sheep at each other.
