The mass schooling was found to be ineffective. First, it was too abstract and static: kids were forced to seat for hours and passively watch the endless streams of information with no practical use. Second, mass school didn't teach the most important subject - social life; while kids were concentrated on unified tests’ grades, isolated school environment left no room neither time for studying various social roles and relations (except for cheating and bullying).
That's why many people abandoned public schools in favor of personalized education - governesses and tutors are popular again. Yet they are not simple babysitters: it's a renewed profession that requires the ability to provide actual knowledge and healthy role models for social behavior though very practical lessons - more like research expeditions or real experience in various jobs rather than abstract classroom study.
Unfortunately, only people with good income can afford such a skilled gouverneur - a human one. For others, AI tutors are promoted as an affordable substitute. An AI tutor is a more profound version of a personal AI assistant: it can provide a child with "educational hints" via dialogs, games and other activities. Since an AI tutor collects a lot of personal info about a child, it can analyze his abilities and talents to create a personalized training plan. Of course, an AI tutor itself cannot pose as a role model, but it creates a virtual personage, a sort of super-hero to follow, based on kid’s interests and favorite games - this virtual friend accompanies a child everywhere and trains his social interactions.
