Steady progress has been made in developing tools to achieve high fidelity control of complex quantum systems. Within the plethora of techniques shortcuts to adiabaticity present a uniquely insightful perspective since they are often analytically determined. By knowing precisely how to suppress an otherwise non-equilibrium dynamics, in this discussion I will argue that quantum control provides a versatile window through which one can study and understand these processes, albeit not without some limitations. This will be explicitly demonstrated by recovering the correct Kibble-Zurek scaling from the quantum speed limit for the controlled dynamics.
