Good episode and apparently interesting book discussed 
Incidental thoughts:
When you search for a word, you don't have a map of statistical likelihood of the word appearing, you start from the concept/shape of what you want to say.
Nice thought about "you wouldn't let dolphin be a judge, despite them being intelligent"
Why won't ai believers relay all their life to chatgpt and stop fearing death? You have immortalized yourself allegedly then.
Also interesting thought about godel incompleteness applying between matrix operation and natural neural networks
They are both introductory, but the first part is more focused, this one is more rambly. They haven't reached the book yet, more discussing author and his ideas in general
