If you were to design an entire ATC system from scratch (pilot interfaces, sensors everywhere in the airport and planes etc) it can be automated. But with pilots having to actually talk to ATC (and sometimes talk over each other with no feedback) instead of observing their status on a screen and pressing buttons on what they want to do or change their status it seems like it will be quite hopeless for quite some time.
What you can probably do is create software which observes traffic and simulates it into the future and notifies the human ATCs about risks. It might even be a good idea to try and digitize it for the ATCs so they talk less and press buttons more (which will feed into the simulation) and use TTS for the legacy transmissions to pilots that don't have an updated interface. Given the regulation on that industry it seems unlikely anyone competent enough to do it will have an interest to even try.
