The SOTA is augmented ATC displays and digital towers, which basically use object recognition to label planes on cameras, and the controllers sit somewhere else. Usually this is done for rural airports, where you have one controller potentially managing multiple low traffic airports, and it’s tough to get ATC willing to move to remote locations. The only busy airport doing this kind of thing is London City Airport, but that has 3M passengers a year and DCA has 25M. That was motivated by the lack of space at London City Airport, so they demolished the traditional tower to reallocate space.
