Oh no, it will be cyclical. Programming is all about attaining higher abstractions, hiding more technology under a simple interface. Every now and then some new set of abstractions will be useful enough that we'll need a bunch of people to explore a field of opportunity. These explorers are called entrepreneurs.

Maybe in 2016, you're going to need deep credentials to be a useful web dev, but none whatsoever to start something useful with 3-D printing.

EDIT: that said, nothing makes you more employable than knowing things at a deep level. A friend of mine, a former Plan 9 kernel contributor, quit the tech industry after the first bubble to become a wildlands firefighter. Returned to the tech industry in 2008 and resumed being a highly-paid infrastructure geek like nothing had happened.

I really agree with this.
