It would be really interesting to have this slowed down and annotated, like DVD commentary. I saw a few things that were like little flashes of insight into PG's mind, and it would be really cool to hear them elaborated. Simple example: changing a word to "claiming" instead of just "saying". I think he rightly assumed that people would feel he was less invested in what he was saying with the original term.

Multiply insights like that by every edit he makes, and assume most edits are significantly less obvious, and you end up with some seriously interesting content.

Reminds me a bit of Hunter S Thompson famously typing out a The Great Gatsby in full, just so he could feel what it was like to write a masterpiece.
