My first brain either has a hoarding problem or runs a big data strategy (cheaper to store stuff than to figure out what it means). Most things I take note of and file away unconsciously are never used, but a chunk turns out to be salient to something 1-10 years later.

This is radically cheaper than taking notes which requires some immediate sensemaking.
But it’s not efficient predictive processing. I don’t primarily store violations of expectations to improve predictability. It’s more random.

Second brain is for processing and digesting and turning into output.

What do you feel is the use of your second brain then, given this?

Often recall-use events are their own reward. Long-arc callbacks are fun for no reason other than being long. I do this in twitter replies whenever I can. Serves no real purpose, but fun to throw people off balance by pointing to an interaction weeks or months ago. Memory stunt.

The only practical use I know of is to impress interviewers. Most people have like 1-minute memory in live conversations. 20+ minutes callbacks look like genius. Iirc sheep on,y have ~20min short-term memory.

With a few cue notes, my near-total conversational recall memory lasts about a week (so the most I can delay writing up proper meeting notes is about 4-5 days adher which there is sharp degradation).

For long-term stuff, what sticks shapes and constrains what I think, not the other way around. I kinda live in the light-cone of my unconscious memory. I don’t really journal or practice any other comprehensive capture habits, which is why the Roam daily note model is not for me.
