🧪 Education Lifelong Learning Simulation

Lifelong learning is not a single curve but a portfolio problem: a working career means continually splitting a fixed number of learning hours across several skills at once, each with its own growth ceiling, its own rate of decay when neglected, and its own shifting market value. This simulator models a 40-year career as five skills — coding, a second language, finance, physical fitness and public speaking — each evolving under a growth-minus-decay differential equation, driven live by how you allocate a 40-hour weekly learning budget. Watch skills plateau under diminishing returns, atrophy the moment you stop investing in them, and track a single human-capital score that rewards keeping the right skills sharp as demand for each one rises and falls over the decades.
