I assume your /s was meta-sarcastic. With a few decades (years?) of refinement, this technology absolutely has the potential to capture private thoughts. Sure, it may require an implant, but just like we all carry tracking beacons that have become indispensable to daily life today, in 20 years it may be “the done thing” to have an implant to control your home automation, etc. Or maybe the tech will improve to where it just needs a hat. And at that point, certain authorities will have no qualms about using it in interrogations, with or without “due process.”
