I can see a similar transition in the future on Ground and Air in terms of departure sequence, the optimum sequence is presented to the controllers, and the 'best' taxy route is suggested.
Unless you only have a single taxy route and no run up areas to integrate with GA.
Controllers won't go away by any means, but the job at the major airports will be very different in 10-15 years than it is now.
Hurrah for the minor airports - keeping their place as the best apprenticeship for controllers.
