Would others agree that this has to have something to do with the amount of time and energy we are increasingly afforded to spend on education? We are becoming smarter about how to education students. Therefore people can pass down those developmental hand-ups to their children, so on and so forth for 75 years. 

We also live in a more complicated world than people did 75 years ago, which requires people's minds to adapt to the changes that have come our way. 

I find that this statement is particularly true of myself and my learners. We tend to learn well in a particular mode when we first learn about how that mode works best, have it modeled, practice it. When we have left that mode and come back to it after having left it for a while (two weeks or more), we tend to need more guidance with that mode on how to use it effectively.  Like everything else in teaching, model, model, model and everything in moderation. 

This is a really good point to make to those colleagues that are tech. unsaavy, hesitant, or unwilling because it "makes us" not as deep of readers.
