It likely doesn't really change anything, and, might even make things worse.
You haven't eliminated the need for school, firstly, as the study of civics and history are core parts of education that really cannot be ignored. You're also ignoring literature and other large swaths of important topics. Also lacking any practical knowledge. Let me be blunt about this: civics are more important to everyday life than chemistry. History is more important to everyday life than physics. Literature is more important to everyday life than calculus. About the ONLY actual important topic being taught by your machines is perhaps "economics", but which economics? There's considerable conflict and economics, despite its pretenses to being a "hard science" is really just a form of philosophy combined with sociology and math. Given you're putting the date at 1945, I presume it will be teaching the then dominate school of economics: Keynesian, which, well, was pretty much followed by the book from 1945 to the 1970s and directly led to a massive economic crisis that Keynesian economics LITERALLY said could not happen, but it did anyway, and was not corrected until the Monist School of Economics from Chicago became dominate in the 1980s.
Culture is also likely to stagnate quite a bit without the teaching of literature, people's writing will generally degrade as teaching writing without teaching literature results in plain, boring writing.
Why is all this? Despite what so many folks might feel, humans are inherently creatures of stories. Culture is built through the stories we tell each other and our children. History is the story we tell of our past. When you eliminate all stories from education, as you're doing here, you destroy shared culture. Further, by eliminating history, you also eliminate important cautionary stories. The saying "Those who ignore history are doomed to repeat it" does not come from nowhere, after all, rather, it is an observation firmly founded in observations of the past.
Oh, you've also likely made communism MORE likely to be adopted by many people. Without the historical perspective on their atrocities and without the education on the human condition provided by religion and philosophy, communism sounds really good and scientific.
Oh, also, without schools you atomize communities fairly badly, as schools often served as communal hubs for children and colleges have long provided critical networking and contacts for people beyond their communities.
Overall, I think this ends up with people having a greater knowledge of the sciences, while having lesser knowledge of their culture, community, and humanity. This goes nowhere good in the long run.
