Karen Hao’s book covers it. But essentially correct. A bit of detail with the family stuff but we do know the guy is machiavellian , a shapeshifter , and that the family did turn their backs on his sister who was effectively homeless and had to turn to prostitution. Needless to say Sam wasnt short of a penny prior to OpenAI days even . Hao is a decent journalist, and her book is the best summary so far I think. This stuff is less interesting than the rest to me however but I guess posing questions of character such as this can help paint the picture.
