Auto,
In some of these things it isn't age that has anything to do with it. Either some people just don't 'get' it or they just wont change their habits. Let me give a perfect example; Inked Area Limits as 0,0 in Paperspace. This concept was so difficult for most to get used to and or adopt, that finally Autodesk gave in and in recent versions the user may chose to let the Edge of Paper be 0,0 OR for those that got it Inked Area Limits. Why? I don't think it was age related, it had to do with folks who did, and still do use 'plot dots' too figure out what to plot when they plot By Window not by Layout, because they just can't or wont change their process, habits, or whatever.
Often my biggest challenge when teaching users MAP, or Civil 3D is to get them to let go of their old processes, and use the software in it's most effective way. Often they have developed a work flow that doesn't, only they don't want to embrace anything new or different. Even if their way is less than optimal, it 'works' for them, even when they can't see the lost profits, or efficiencies of doing so.
