Many of the skills that were important in the past will not be or are not important now or in the future.
Writing in cursive? Archaic. Forget that I got graded on it in grade school.... It's not required today.
I've seen teens of today communicate. Looks like they communicate among themselves just fine. I may not understand it, but I'm also archaic.
New times, new ways. The rate of change will only increase.
But can they communicate well with anyone outside their peer group?
