Did not read the book, but have been following OpenAI since the beginning. The whole thing comes across as a bait and switch with parallels to Google's "Don't be evil." At minimum he isn't a person whom comes across as trustworthy - but very few tech leaders (or politicians, etc.) do.
This situation is arguably better than an alternative where Google or another big tech monopoly had also monopolized LLMs (which seems like the most likely winner otherwise, however they may have also never voluntarily ventured in to publicly releasing LLM tools because of the copyright issues and risk of cannibalizing their existing ad business.) Feels like this story isn't finished and writing a book is premature.
