It really does feel like there is a gigantic competency bubble that is about to pop.

The amount of people who are willing to learn the hard systems and businesses is dwindling by the day. You think its difficult to find airline pilots and truckers? Try to find a developer with both the domain knowledge and technical skills to fix a custom piece of code in a community bank's core system that was written in 1994. Oh, and we need it fixed before close of business or our fedwire files are going to be totally fucked...

The amount of money they will have to offer to capture the appropriate talent to keep their businesses running is going to become astronomical. The executives sometimes try to take a quick path out of this hell and usually wind up with 1 additional reason they have to stay. The most common mistake is attempting a full vertical swap-out, followed by paying some firm to explain that your shit sucks by way of installing some middleware in your infrastructure and telling you things you already know.
