Most ideas exit
the zeitgeist as quickly
as they enter. The
ones that last tend
to offer something new:
a powerful argument,
a fresh perspective,
a sign of things to come.
From political crises to
technological revolutions,
from fast food to fashion,
the ideas that shaped this
year are wildly different.
But odds are you’ve had
a conversation—maybe
even a debate—about
at least one of them.
Likely more.
