I don't see the need for facial recognition technology in classrooms. Would it serve to control, to supervise or to manipulate? Maybe it is used in other environments and by other people, could be considered prudent, but I really do not see the need to use these mechanisms in schools. If they want to know what kind of people they have as students, ideally there should be supervisors, teachers, who do that work. Every day I am impressed by the amount of private information that the technology of each one of us has. Without realizing it, we give confidential information to certain devices without knowing where it will end up. Last year it was made public that a website in Russia was given the task of publishing the faces, with their respective names, of those attending demonstrations in favor of opponents of President Vladimir Putin using facial recognition. Some technologies, in dangerous hands, can also be a danger. Thank you for this post, @techblogger
