I am not sure if this has been well enough discussed elsewhere regarding Project Lawful, but it is worth reading despite some fairly high value-of-an-hour multiplied by the huge time commitment and the specifics of how it is written adds many more elements to "pros" side of the general "pros and cons" considerations of reading fiction.

It is also probably worth reading even if you've got a low tolerance for sexual themes - as long as that isn't so low that you'd feel injured by having to read that sorta thing.

If you've ever wondered why Eliezer describes himself as a decision theorist, this is the work that I'd say will help you understand what that concept looks like in his worldview.

I read it first in the Glowfic format, and since enough time had passed since finishing it when I found the Askwho AI audiobook version, I also started listening to that.

It was taken off of one of the sites hosting for TOS, and so I've since been following it update to update on Spotify.

Takeaways from both formats:

Glowfic is still superior if you have the internal motivation circuits for reading books in text. The format includes reference images for the characters in different poses/expressions to follow along with the role playing. The text often includes equations, lists of numbers, or things written on whiteboards which are hard to follow in pure audio format. There are also in-line external links for references made in the work - including things like background music to play during certain scenes.

(I recommend listening to the music anytime you see a link to a song.)

This being said, Askwho's AI audiobook is the best member of its format I've seen so far. If you have never listened to another AI voiced audiobook, I'd almost recommend not starting with this one, because you risk not appreciating it as much as it deserves, and simultaneously you will ruin your chances of being able to happily listen to other audiobooks done with AI. This is, of course, a joke. I do recommend listening to it even if it's the first AI audiobook you'll ever listen to - it deserves being given a shot, even by someone skeptical of the concept.

I think a good compromise position, with the audio version is to listen to chapters with lecture content with the glowfic in another tab, in "100 posts per page" mode, on the page containing the rough start-to-end transcript for that episode. Some of the discussion you will likely be able to follow in working memory while staring at a waiting room wall, but good luck on heavily-math stuff. If you're driving and get to heavy-math, it'd probably also be a good idea to just have that section open on your phone so you can scroll through those parts again 10 minutes later while you're waiting for your friend to meet you out in the parking lot.

TL;DR - IMO Project Lawful is worth reading for basically everyone, despite length and other tiny flinches from content/genre/format. Glowfic format has major benefits, but Askwho did a extraordinarily good job at making the AI-voiced format work. You should probably have the glowfic open somewhere alongside the audiobook, since some things are going to be lost if you're trying to do it purely as an audiobook.
