When the environment is energetic enough, the electromagnetic force and the weak force unify into the electroweak force. The weak interaction controls radioactive decay.
We can control electromagnetic force "at scale", IMO. It's not freely, but we have networks of electromagnetic systems that span continents.
If we could control the weak force at the same scale... I'm not sure what wonders we might unlock. At the very least, I imagine we could "clean" instead of just "contain" radioactive waste, at least low-level stuff.

Corollary / Contrapositive: Any technology distinguishable from magic is insufficiently advanced.
