We talk about a wide variety of stuff on LW, but we don't spend much time trying to identify the very highest-utility stuff to discuss and promoting additional discussion of it. This thread is a stab at that. Since it's just comments, you can feel more comfortable bringing up ideas that might be wrong or unoriginal (but nevertheless have relatively high expected value, since existential risks are such an important topic).
It is good idea. But anyway booklenth format is obsolete - that is why sequenses in LW is more popular then earlier booklenth Creating Friendly AI. So for the book it is better to be cut on wiki pages of chapter lenth. Another problem is luck of interest - I could create such wiki but most likely nobody would visit it. Anyway may be I should create it and invite people to try and add information.
What about editing and releasing chapters as posts on LW for discussion as each chapter is completed?
