Most of the technical problems with learning/teaching are actually caused by sticking to outdated 19th century concepts in schools such as having the (by definition average) local teacher explain things instead of someone who actually knows how to explain the subject matter well and pretending that kids need to memorize everything in a modern world instead of incorporating the ability to look up things into the learning process.

Most of the actual major problems with education are caused by funding structures and deliberate sabotage by parts of society who benefit from an uneducated population without critical thinking and research skills.
