Keep AI Out of Your Obsidian Vault
It's so hard to finish an idea that is not yours (and suggested by AI)
The author argues that using AI to generate notes or connections in Obsidian is a dead end. AI-generated summaries become noise, and you lose the thinking that comes from making your own links. They recommend using AI for research or separate experiments, but keeping your main vault human-curated for long-term value and insight.

I have this problem even in codebases. Claude will work on something, and add detailed comments in which it extrapolates the from the design and confidently states intentions and decisions which aren't actually grounded in reality. Then, later sessions suffer when it reads back those hallucinations and treats them as canonical.

I don't get the second brain thing. I don't keep a second brain, I just read and think a lot. I once did a physics masters and, when asked how to make steady progress, one of the professors (who had published with Paul Dirac no less) made the comment "well, my secret is that I think about physics all the time"
I started practicing this for the stuff I'm interested in ... and the result is that I generate a lot of ideas. 99% of them are garbage.
Before AI, a conversation with colleagues would help me weed out the garbage, and possibly give me a new perspective ("here's something surprising about what you just said!")
Now, AI plays a helpful role in helping me weed out the garbage for the subset of ideas that I can test empirically -- and sometimes it does give me a new perspective, but with significantly more noise than my colleagues, who would take me right to the point that would be useful for me to see.
I've never felt like I needed a second brain ... because if I had such a thing, I think I would be keeping the 99% garbage around -- instead I just let biology GC it.

Ironically, this is why one of the best ways to manage upwards is to prompt managers into coming up with your idea as if it were their own: they’re dramatically more likely to execute and deliver on it. Of course, this also obviously leads to undue credit given for coming up the idea, which is certainly a core problem with AI as well, but it’s still charming to watch managerial psych being rediscovered by this new generation of managers.

ive never been able to use zettelkattsen. i like having daily notes instead of different notes for different ideas. its easier this way. my obsidian vault is a hybrid of diary and research and i am trying to separate the diary and research but its not easy tbh. (i suffer from a crushing urge to note that i "just ate a sandwich, was good" while liveblogging research and debugging.)
that being said, i got a big kick out of feeding my daily notes into my local model. i had some more diary-like entries that i would never share with anyone, but it was extremely funny to have my local model take a 3000 word recap of what i did in a day and summarize it like "writer reflects on their job: they worry about their performance. meals: the writer ate oatmeal, and a sandwich. family: the author contemplates their fathers absence growing up."
ive developed a really large corpus of written work over the years and am hoping to fine tune a model using my diary as the training set. i think this would yield hilarious results. keeping it all local though, i drop my passwords in there at times and i dont want that leaked.

Could anyone enlighten me as to why to use Obsidian in one's daily life ?
I have a dozen ideas popping a day and nothing comes close in terms of ease than a paper notebook for capturing and some apple notes equivalent for storage.
Used to have a Notion but all the "Second Brain" movement seems...fishy to me ?

Yes! And that's because you can't really delegate ownership/authorship to AI (at today's capability levels). Coding agents might have been RL'd out the wazoo to write code to solve well defined problems, but given a situation the onus of making sense of the ambiguity and identifying the problem -- and even crafting a skeleton for an acceptable solution keeping in mind tradeoffs -- needs to be done by a human taking ownership.
I wrote about this recently from a slightly different angle [1], but the core idea is the same -- which is why it is hard to take over an idea mooted by AI. Before even writing/implementing, the AI has internally resolved ambiguity with several decisions which are arbitrary, and match neither your mental model nor the actual ground reality (which you need to spend time understanding in order to productively interpret).

As the author does, i just have a separate vault for AI to manage.
It used to be a mess, but with OKF (Open Knowledge Format), things are more manageable and navigatable (for me as well).
Consider AI vault as a scratch pad that AIs use, not as something you put your own thought into it.
