A properly designed T2 obviously won't transfer information between different parts of it's system as text on top of video. This new DR0NE seems to be Robocop style, human inside machine, but even in this case I bet there are more efficient channels.
This transition in modern armies from soldiers to different types of drones really scares me. Drones can easily be deployed on home soil against any kind of anti-government protests. The government would need just a few hundred of loyal operators to command a huge force.
Looking at history, the only times and societies where democracies and republics were established - e.g. Ancient Greece and Rome, France, US - were those were free citizens had access and could afford weapons similar to those used by the elite. With the transition to military drones in Western society I'm afraid the democracy will also transition to totalitarianism.
Blades in huge datacenters are not serviced one by one. Typically you'd wait until say 20% of the blades fail and only then fix and upgrade the whole rack at once.
