For example, one of the most chilling aspects was the telescreen to me. The horror of telescreens was that someone could maybe be watching, even in your own home. Quote: "There was of course no way of knowing whether you were being watched at any given moment". Now this has been exceeded by technological mass surveillance - basically we ARE being watched nonstop. A panopticon effect is replaced by a robot sitting and staring 24/7. Everything I say is stored forever; further, machine learning can effectively filter through all of our civilisation's data and, even far in the future when attitudes change, red flag anything I say which is deemed unacceptable. Pegasus malware can turn my smartphone into a listening and viewing device at any time. I can barely even use cash in my country anymore, so this is extending to all purchases. This is BEYOND what Orwell could envision. It is shocking that people have somehow come to accept and normalise this feeling of being watched.
I could go on and refer to hundreds of similar aspects.
