In just a little over four years, we’ll be living in the ‘20s. We’re almost back to the whole two-digit decades thing, and some of us are actually going to be alive in the ‘60s and stuff. What we now just call the ‘20s, ‘30s, etc. our kids will see the same way that we view the 1820s, 1830s, and so on.

I’m also curious who will be the very last person alive whose birth year begins with a 1. Of course, I won’t get to find out unless that’s me...
