Gov can now scrutinize candidates for secretive organisations en masse for even the lowest positions and effectively weed out anyone who's ever shown even a hint of dissent, morality or adherence to principles who've proven to be any kind of risk against total obedience.
Gov can now also monitor employees' every heartbeat, every step, sleep patterns, stress levels and every spoken word (literally true for all of these), let alone their actions.
The risk of getting someone like Ellsberg past the door, let alone at any meaningful level, can now be crushed at previously unthinkable values.
How would these improved, airtight, secretive organisations operate and what would be the consequences? It feels like all these advancements in tech placed us on a one way superhighway towards returning to empires, aristocracies, eternal ruling classes & eternal commoners.
