I can imagine that many people in positions of power would read the article above and immediately think about introducing it in schools, universities, and other educational institutions.
They would say, “No need for exams, we just monitor your brain waves during the classes and calculate your attention throughout the semester. At the end, we run an algorithm to determine if you passed the class. Perfect, right?!”.
Hell no, not perfect and not the place we should be aiming to go. Again, they will say “but you can opt out” and that will be a lie. You will be coerced to abide by the norm or social pressure to join and have your brainwaves monitored. “Everyone is doing that, why don’t you?”.
The next frontier is our brains, the oppression of thought and behavior at the source. đź§
