Another case in point is that memorizing vocabularies and grammar, although could seem like an efficient way to learn a language, is incredibly unrewarding. I've been learning japanese from scratch, using only real speech to absorb new words, without using dictionaries and anything else much. The first feeling of reward came immediately when I learned that "arigatou" means thanks (although I terribly misheard how the word sounded, but hey, at least I heard it). Then after 6 month, when I could catch and understand some simple phrases. After 6-7 years I can understand about 80% of any given speech, which is still far, but I gotta say it was a good experience.
With LLM's giving you ready-made answers I feel like it's the same. It's not as rewarding because you haven't obtained the answer yourself. Although it did feel rewarding when I was interrogating an LLM about how CSRF works and it said I asked a great question when I asked whether it only applies to forms because it seems like fetch has a different kind of browser protection.
