Great point. I was looking at education tech, and I think education is not a "solvable problem". Retention and mastery Remain the two ends of the success spectrum. But where a student lies on that spectrum depends on a lot of variables, several of which directly link to economic outcomes in the nation such as 1) nutrition levels of parent and grand parent (in particular female education) 2) nutrition availability 3) average household wealth 4) child labor (more importantly - the necessity for children to work to keep the family unit going) 5) country stability (no war is an obvious one) 6) teacher quality and school funding These in turn impact very personal variables that determine how students codify information such as 1) student age (children vs an adult who needs to retrain while keeping a family afloat) 2) learning style 3) mastery of language of education, and mastery of the language of higher education (multi language societies have to Deal with this) 4) stress 5) health and health availability 6) freedom to study (if you are a girl child, or Of the wrong tribe/caste/color/religion) And this doesn't account for many other variables such as people actively trying to teach you falsehoods or bad syllabi (sort of part of the education quality) And this entire system does not exist in a vaccum - parents tend to push kids into education streams which improve job options, hence the demand for STEM.
