"What's really happening inside the AI agent memory infrastructure war?"

No fucking idea. I've not invested nearly the energy necessary to really understand this piece of the infrastructure. No promise on accuracy, and this is also a bit of a public bookmark, but I'm finding it interesting. The creator seems to have other quality stuff brewing in there, as well.

I should have already heard about Karpathy's Wiki (in the context of using Obsidian, potentially), but I didn't. This, also, from same, is interesting: Karpathy's Wiki vs. Open Brain. One Fails When You Need It Most. 

Which also means I should probably experiment with Open Brain. Maybe it's garbage. No idea.
