Still, I feel like this mostly applies to strict memorization. I've never really had to memorize stuff outside of academic curriculum. In a real-world setting, at least in my case, it's much more about processing ideas, interlinking data points, seeing patterns, categorizing information, etc. Doesn't matter if you're trying to understand a development framework or a personal relationship, it's about intimately understanding a small amount of data rather than coldly memorizing an entire database.
Still, great article, the example was awesome
