Pilotless aircrafts coupled up with a controllerless ATC... Doing everything from pushback, taxiing, taking off, sequencing, spacing, landing , taxiing to gate. All the performancedata directly from the aircrafts to the ATC computer, every little detail, like fuel remaining, performance, problems and so forth. The ultimate system, totally independant and without humans to mess it up.
You're already electing to fly the RNAV approaches, cause it's easier to let the computer, controllers let you, cause it's easier than vectoring, so in a lot of points the system is developing itself to one where we all sit on the sideline and monitor.
Sure, an aircraft will crash from time to time, but then we'll file a report to the geeks in programming and they'll fix it.
I'm pretty sure that'll be the future....
