Learning is such an incredibly interesting topic for me. The concept behind something like machine learning is easy enough to understand- especially since you can implement everything by yourself and know exactly how it works. 'Human learning' is just so spectacularly abstracted from these models that it leaves me wondering how the heck we actually learn anything. Some examples like your piano playing and muscle memory are some of the more straightforward ones, where we figure something out like 'oh, this section is easier to play with this fingering'. But, like, you're not consciously drawing on all your previous conversations whenever you talk with someone and you don't think 'that conversation went well, time to add this to my corpus of conversations and retrain my "how to speak" module.'
I think it's beautiful that we'll never figure out exactly how learning works.
