I think they're for investors.

Ask Gemini to summarize it? Or maybe NotebookLM to turn it into a 10-minute podcast? :-)

I don't read them, but I listen to them on my commute (with a saas I made).

I do, just for fun. It's become sort of a hobby, learning more depth/detail behind the current AI arms race. It certainly cuts through the shallow takes that get thrown around constantly.
