I don't think I'm your survey target, as cost/benefit fails all along that "second brain" pipeline have so far prevented my non-trivially adopting one into my extended mind. But thank you for surfacing a "now with LLMs and speech-to-text, I should revisit". Like a git docs dir, a "second brain"-ish pkm fragment might be a fruitful setting for LLM communication/collaboration/RAG.
