  The character of jets is dominated by the influence of intrinsically
nonabelian gauge dynamics. These proven insights into fundamental physics
ramify in many directions, and are far from being exhausted. I will discuss
three rewarding explorations from my own experience, whose point of departure
is the hard Yang-Mills interaction, and whose end is not yet in sight. Given an
insight so profound and fruitful as Yang and Mills brought us, it is in order
to try to consider its broadest implications, which I attempt at the end.
