I don't think there is a device per se, but that is the purpose of Google. Archive what people search for. Record how they search for it. Analyze which results they click, impressions etc. Google Analytics.

Once you have enough data, you no longer need to read the mind as you can accurately predict what is going through that mind.

Bonus - they feed all this data to AI server farms so the AI can learn.

Extra point - funded and setup by the deep state folks so they can keep an eye on you too!

To what end? And what could mind readers gain that simple online data couldn't obtain? I agree that there is untapped human abilities of the mind and as much of a cuck as he is I agree with Steven king that most of is share a low grade telepathy. So are more naturally gifted of course and some work for it. To this day my mom denies it but when I was six I told her I could hear people's thoughts and she pulled me to the side and told me I'm never to tell anyone this and should stop. She worked taking care of retards and probably didn't want me being labeled one but I swear I'd hear their thoughts and say them and that wide eyed look of confusion was confirmation in my little mind. Oh well
