In the U.S. the Baby Boom generation includes anyone born from 1946-64, which means everyone 41-59 years old. Those ages generally cover the top technical management positions in most companies and universities and they are starting to retire. But as anyone who reads magazines knows, this generation of upcoming retirees acts younger and healthier than the generations that preceded it and they plan to have very active older years. At the urging of reader Joel Franusic, I've been thinking of what implications this has for Open Source software.The implications are huge. Imagine 100,000 engineers and programmers leaving the U.S. work force every year for the next 18 years, because that's what is going to happen. Some of those people will find other careers, but most of them will be motivated less by money than they were earlier in their lives. Most of them will want to remain active. And once a nerd always a nerd, so I think many of them will gravitate to Open Source.
