Anyone who thinks the younger generation isn't already both well versed on enterprise software development and actively contributing to its progression is either delusional or stupid.

Completely agree that experience means a lot in the software world, but it doesn't mean everything. Speaking as a 25 year old enterprise software developer working for a Fortune 50 company, I constantly see developers even younger than myself running circles around the older folks. That's not to say the guys with 30 years of experience under their belts aren't valuable, I'm just saying that younger engineers can add equivalent value.

It appears to me that anyone who thinks they can run a development shop with people who are 30 and older only has one fate, and that's rendering themselves irrelevant. The younger generation is what pushes technology in new directions, and without any of them on your team, you'll be spending most of your time looking at the help wanted ads and the obituaries.
