It's the evergreen tradeoff between the short and long terms. Do I get the nugget of information I need right now but lose in a month, or do I spend the time and energy that leads to deeper understanding and years-long retention of the knowledge?

There is something about our biology that makes us learn better when we struggle. There are many concepts on this dynamic: generation effect, testing effect, spacing effect, desirable difficulties, productive failure...it all converges on the same phenomenon where the easier it is to learn, the worse we learn.

Take K-12 for instance. As computing technology is further and further integrated into education, cognitive performance decreases in a near-linear relationship. Gen Z is famously the first generation to perform worse in every cognitive measure than previous generations, for as long as we've been recording since the 19th century. An uncomfortable truth emerging from studies on electronics usage in schools is that it isn't just the phones driving this. It's more so the Duolingo effect of software overall emulating the sensation of learning without actually changing the brain state. Because the software that actually challenges you is not as engaging or enjoyable.

How you learn, and your ability to parse, infer, and derive meaning from large bodies of information, is increasingly a differentiator in both the personal and professional worlds. It's even more so the case when many of your peers are now learning through LLM-generated summaries averaging just 300 words, perhaps skimming outputs around 1,000 words in length for "important information". The immediate benefits are obvious, but the cost of outsourcing that cognitive work gets lost in the convenience.

Because remember, this isn't just about your ability to recall specific regex, follow a syntax convention, or how much code you ship in an hour. Your brain needs exercise, and deep learning is one of the most reliable ways to get it. Doubly true if you're not even writing your own class names.

What I am speaking to is not far away or hypothetical, either. Because as of 2023, one in four young adults in the United States is functionally illiterate.

Effective learning and memorizing is actually at the narrow edge of struggling: it's neither "too easy" nor "too hard and painful". SRS systems do a very good job of tuning this: by the time a question comes back to you it will feel difficult, but you'll be able to recall the information and answer it with some effort. It's a matter of recognizing this feeling and acknowledging as "the right kind of effort" as opposed to a hopeless task.

If you ask the AI "please quiz me about the proper understanding of issues x y z and tell me if I got it all right. iterate for anything I get seriously wrong, then provide a summary at the end and generate SRS cards for me to train on" it will generally do a remarkably good job at that.
