"Rationality from AI to Zombies" - I loved that book! It took me quite a bit to read it all, even though it is written in a colloquial style (might be due to length or me just wanting to digest what I've just read). Changed my perspective on quite a lot too, mainly how to approach information that causes cognitive dissonance.
I wanted to read some of it again for some time, so I thank you for pointing out that there is an audio version now!
I stumbled on his videos a couple of months ago. Sadly, I only realized yesterday that there were captions that described his process, but watching it without isn't too bad either. He does things in a very evident manner and it's pretty relaxing just watching him do his thing.
Yes, I think that is the main reason people enjoy his videos. I remember him stating somewhere, that he wanted to make this type of videos, because when he watches instructional videos, he always skips to the part where things are shown (and there is no talking).
