I love how they credit some random guy as if he innovated the journal. Leonardo Da Vinci, Thomas Jefferson, and Marcus Aurelius surely didn't do this before with the technology available at their times.
Tom Negrino and Dori Smith had a weblog called Backup Brain back in 2000.
Or just use Logseq/Roam/Reflect/Obsidian etc
I like this concept under the premise of having an unlimited (or highly unconstrained) LLM manage the repository -- preferably locally hosted.
A simple dumb repository of notes is less interesting to me.
yeah self hosted low power LLM's is what I'm waiting for.
