Time for clickable text messaging for ATC instead of voice.
Which I suppose many of us already have and use in the shape of CPDLC, but in it's current iteration I can't see it being an improvement on "voice" in a busy terminal area ( though it's great in remote areas) ...
I'd pity the poor controllers trying to shuffle the Heathrow arrivals solely through CPDLC...each controller would probably need a dozen "scribes" or more if things started to go off script.
