What will they see in their lifetimes? Will they (and I) be able to adapt to all the changes? What gadgets will we be using in 2050? I'll be 68, if I'm still around and my kids will be 41 and 37, probably with kids of their own. I hope to be using the latest communication technology, whatever it is, unless it's against my beliefs somehow.
My grandfather was more up-to-date on digital equipment than I was and he never stopped learning about cutting edge technology. Even if I have to take classes for senior citizens, I'd like to know what my grandkids are talking about. :-)
