Terrain safe
I doubt very much that towers will be exempt from technology creep - particularly those at airports with little/no vfr traffic to speak of.
Digital/remote towers, artificial intelligence, safety prompts (e.g. Oi, Tower controller, I sense the departure isn’t rolling yet and the next arrival will be over the tarmac before your departure gets airborne...gonna do something about it??).
And before anyone shouts about “but that’s what you have eyes for!” then why do we already have RIMCAS, SAMAX, etc, etc, etc...
