We're talking about undergraduate degree programs, which for STEM consist substantially of problem sets and tests that have right answers. Sometimes they're just answers, sometimes they're more like Pareto frontiers, sometimes they're programs, but in any case the bulk of the work is verifiable, which is a luxury. It's a bit (but only a bit) like the difference between solving a chess puzzle and actually playing chess. We teach people with puzzles, then send them out into the world to play real games.
