And it's not even implausible. Real time data collection of what it is you're looking at, eye tracking to determine what it is you're focusing on, biometric data also collected in real time to measure your physiological response, throw all this into an AI to analize and effectively someone can know what you're thinking at all times. See two men kissing, have a disgust reaction, and you get flagged as being homophobic. See a police bodycam video of a black thug getting blasted and have a positive reaction, and you get flagged as being racist. Read a post about how the holocaust was fake and the jews rule the banks and don't have an angry reaction, and you get flagged as being antisemitic. So on and and so fourth.
