Simple, just build in some escalation mechanism. Pilots should be able to get to talk to a human, and be listening in on the exchanges in case their attention is required. Of course, insisting on heavy handed, laborious, and error prone human exchanges all the time has its own risks. ATC getting overloaded with more traffic is a given either way. Loads of electrical drones will start showing up in the next decades. Some piloted, some autonomous. ATC will have to adjust to that. And keeping everything the same with more human controllers is not going to scale.
