I can tell you in my case, older folks who still program can be VERY picky on what new tools they elect to invest time in learning. When we elect to "keep up", we do it in the general case and I'll tell you why from my point of view, there have been times in my life when I've chosen to dive into details of a tool, that I would then be disappointed in what I discover and now this time is spent, I cannot get this time back. When we're young, time is cheap. Look, "keeping up in detail" is the domain for youth because youth has the luxury of the spare time to do it. Besides, being left behind is actually the destination for all of us simply as the result of our own mortality. I'm suspicious that you might think that the fact some folks "haven't kept up" indicates an error on their part rather than a very valid choice. heh and in my case I'm just not that good a programmer so theres that.
