I mean, it depends.

Like, unless it is somehow relevant to your daily life knowing the capital of Nova Scotia is literally useless. Same with all the history I learned in middle school. Remembering takes repetition, and so retaining the information I learn needs a habit of review and processing. And a lack thereof (alongside the brain seeking to offload information, bc information is expensive) is why you forgot the capital city.

I find I remember things best when I jot them down, and personally I’ve been needing to journal more, writing down my ideas and what I learn when discussing my ideas with LLMs, though I’ve also noticed that using the LLM as a rubber duck has actively helped my memory due to more review and processing and needing to “teach” my ideas to the model.
