Well, they don't need some super advanced tech to brainwash population across the planet. Take look on all this "small" stuff around. They push his agenda in every occasion. Sometime this are really small stuff, trifles, but cumulative effect is tremendous. I watch a lot YouTube videos. Science, computers, history, etc. In many videos author talk about topic and on screen you have some videos which fill background, people which walk, talk, work with machines, etc. Just fillers. This are stock footage which people buy in bundles on stock market. And if you blink, you miss it. There are disproportionately small number of white people, especially white males. For example there is footage of laboratory and scientists which do "science stuff'. Most of them are gentlemen's and lady's of color, white female. If there are white male, usually there are some black scientist which explain something to him. This don't look significant on first look, right? But think about effect in long run. People are brainwashed to accept that white population are much smaller, that black people are superior to white male, etc. Footage of happy, successful family = black couple or mixed race couple. Footage of losers, primitive, violent people = white male. Footage of scientists = people with surplus of melanin... etc. People often talk about race swap in modern culture, lack of whites in commercials, such stuff. This are visible and make some backlash, people rant, talk about it. But things like this stock footage fly under the radar. But such kind of indoctrination are very dangerous, because this on unconscious level condition people that accept that white are minority, that white are insignificant part of society, that white are worst part of society, etc. Someone push such stuff on stock market. People buy what are available, people buy stuff which are cheap... people don't think about content of this footage. They are interested that video quality is good, that color grading are ok. such technical stuff. They don't count people by race. But someone obviously very carefully care that race - gender representation are according to agenda.
