Orwell never even envisioned this form of state surveillance!

Philip K Dick did at least, in A Scanner Darkly https://en.wikipedia.org/wiki/A_Scanner_Darkly

> When performing his work as an undercover agent, Arctor goes by the name "Fred" and wears a "scramble suit" that conceals his identity from other officers. Then he is able to sit in a police facility and observe his housemates through "holo-scanners", audio-visual surveillance devices that are placed throughout the house.

When will we need to start wearing "scramble suits"

yeah, you needed the tv's to watch you in his world, and even then humans needed to watch the feed, no AI/automated monitoring.
