I would argue that forging evergreen notes is an intrinsically meaningful activity.
I wouldn’t say every evergreen note gets to the level of “wisdom”, but they can, and most rise above the level of “information”. The same is true of higher-order notes like MOCs.
So at the very least, if you’re focused on building evergreen notes (which involves the questions I wrote above and many more), you’re spending attention at a level that can sufficiently satiate a lot of existential angst—while building something that you can age with and rewrite over time.
