The irony is that the US routinely uses much more capable software for almost identical purposes in domains like battle space management. It isn’t like the US doesn’t have this software, more that the FAA doesn’t consider anything derivative of that tech as an option.

My original response was sharper than I intended; I am aware of both the air-defense and ATC systems for both the civilian and military use (so worked in each cell of that mini-2x2 table). The military is much more tolerant of risks and, even if implementing them would lead to an increase in safety and convenience using military systems for civilian ATC will likely cause all sorts of problems due to differences in training, planning, etc.
