The Optimist. By Keach Hagey Empire of AI. By Karen Hao
The reviews are positive for both books. The column itself is titled "Sam Altman is a visionary with a trustworthiness problem" and shows a few reasons people have had some problems with his behaviour. One quote from the article is :
"Ms Livingston fired him, but as Ms Hagey recounts, he left chaos in his wake. Not only was he overseen by a non-functioning board, he had also used YC equity to help lure people to OpenAI. She says some YC partners saw a potential conflict of interest, “or at least an unseemly leveraging of the YC brand for Altman’s personal projects”."
