Than humans and even expert humans. For specific, narrow tasks super human behavior has long been achieved in many classification tasks. Like tumor detection in XRays for example.

ATC jobs are extremely stressful and complex and they have surprisingly little digital support systems. A digital system could for instance easily suggest an optimal route through the airspace based on the aircraft’s capabilities and data and other airplanes in the air space before the pilots even checked in with the ATC. Today ATCs still have to request and suggest course changes via radio even though both them and pilots are sitting in front of computers.
