#GA y'all.
I might as well put this under #bookstr despite an audiobook being listened to for some time a few days ago. I found one called "The Theory of Everything: A Unified Version of Reality" by Ash G (I assume his pseudonym). I found the book on his channel, "The Codex of Everything" on YouTube from a Techlore video he commented on. I was listening to it, and I was surprised how deep it is.
I downloaded it using yt-dlp GUI as an OGG/Vorbis file, and listened to about three hours of it. I was fascinated, though I need to go through the almost 10 hour book (yes, it's long at 26 chapters), but goes through the a theory that's backed up pretty well.

It's highly recommended you download this using yt-dlp, just in case the book gets take down for some reason. I did, and I'd be happy to lead you to the right place, since I don't upload big files right now due to what isn't a skill issue.
