Given that schools are state institutions and teachers are taught to teach in a certain way, which leaves a very large group of children behind, from those who cannot learn from books to the gifted, and everyone is expected to learn in the same way, when students are forced to participate in certain demonstrations because otherwise they will fail, it is certainly brainwashing. This is also the reason why there is a complete lack of knowledge about certain countries or even one's own history and why the average person is not very open-minded towards other cultures. You are free to disagree with my opinion, but who knows, in 35 to 40 years' time, you may think differently.
As for what is taught at school and rarely used in practice, the reverse is also true. Much of what we need in practice, such as filling in tax forms or keeping accounts, is not taught at school. Not to mention the countless forms that people have to fill in during their lives and all the laws that we are bombarded with and that every Dutch person is expected to know. This is ridiculous in itself, given that not every Dutch person has studied law.

As for technology, I assume you mean AI? I have noticed that AI is very American-oriented and influenced. I don't think AI is that super intelligent, but it is incredibly obsequious because as soon as I point out mistakes, I always hear, 'Yes, you're right'.
