Traditionally, the conventional approach to education involves a lot of time and money investment through a comprehensive curriculum. Institutional prestige steps in as a bias; there’s a lot of theory involved, much more than practical experiments, and the earned credential becomes a gatekeeper toward employment, irrespective of whether there’s a skills mismatch with the role in question. In contrast, micro-credentials are like supplements, whereas traditional degrees are full-course meals. Suppose you have an iron deficiency in your body—it wouldn’t make sense to load up on beans, nuts and red meat for every meal. That would be costly, boring and time-consuming. But you can easily supplement with ferrous sulfate or other approved variants and get your iron levels balanced while still enjoying your meals.
